Jake Howell bcb5b43aa7 fix: resolve entitlement check on ai bridge settings/view (#22385)
Resolves cases where the user is entitled to AI Governance but we don't
show them the page because its not enabled. If for some reason the user
doesn't have AI Bridge enabled anymore but still wants to access the old
logs page they now can.

Furthermore, we link to the docs regardless of if they have AI Bridge
enabled, this is inline with our other settings pages.

Jake Howell 6f3385d5e4 fix: resolve stability in scrollbar-gutter: stable (#22387)
Replaces the approach in #22061 (with a cleaner `git history`)

This now ensures that we don't attempt to cause a layout shift when the
sidebars pop-in-out of existence (when scroll locking within `radix`).

Jake Howell 12372c4b1e fix: restore emptystate to <OrganizationProvisionerKeysPageView /> (#22372)
This element was receiving the provisioner key daemons and then
immediately filtering them. This lead to the default state being a table
with nothing rendered rather than the `<TableEmpty />` as we would
expect.

Jake Howell 0bafc05c37 feat: add permission check around <AppearanceSettingsPage /> (#22383)
This previously let auditors view the page though they can't update
anything. In a different fashion to #22382 the user will be able to see
all of this as they're logged in to the application anyway, we can
simply tell them `Sorry, no access`.

Jake Howell 358f521bbb feat: implement error message on failure to popup (#22380)
This change adds user-facing feedback when opening apps in a new window
fails due to popup blocking, replacing a silent no-op with a clear
recovery message. It improves reliability and supportability across
app-launch flows by helping users immediately understand and fix the
issue.

Jake Howell 39093dbd61 feat: implement invalidateQueries instead of location.reload() (#22377)

come across way smooother.

waitFor resolved, causing sporadic act() warnings and timeouts in the
publish template version tests (or so says Claude Sonnet 4.6).

Jake Howell 173299fcec fix: restore dividing line in <BuildParametersPopover /> (#22373)
Related to #22367 

It was pointed out to me that we actually did regress this mildly by
removing a dividing line in the changes made in #22367, I've restored
this in a better way by taking advantage of `divide-y` and wrapping this
in a proper `<div />`.

Jake Howell 6364cfa360 fix: resolve double border on <WorkspaceBuildPageView /> (#22374)
Not sure how I didn't see this before in #22362 , theres a sneaky double
border which makes things slightly thicker than we would expect. This
border should only be showing with the `border-b` and we forget to reset
down to `border-0` first.

Jeremy Ruppel e161083053 fix(site): use cross-browser compatible assertions in MonacoEditor story (#22337)
Switch to asserting only on the onChange spy, which is the actual
component contract being tested. Monaco's textarea value is always empty
regardless of model content, so the toHaveValue assertions were
unreliable anyway.

Fixes the new storybook test introduced in #22202

Jake Howell a51eb40dca fix: marshal convertLicenses() into a [] instead of nil (#22366)
This was a bad smell that was being addressed by the frontend. This type
was generating out to be a `nil`/`null` instead of an empty `License[]`.
Now this returns as an empty array and we can actively check if we have
no licenses with a length of `0`.

exactly how they did before, but with a new shinier coat of paint.

Jake Howell dbc0daa64b feat: add animation to copy button <Check />s (#22319)
This pull-request adds a tiny little animation for the `<Check />` when
the copy button activates. This is inline with how `sonner` does their
animations (means things are a little more uniform).

Jake Howell 54a7ec4b5b fix: resolve borders on <WorkspaceProxyRow /> (#22345)
This pull-request resolves some stupid border issues we were having in
`<WorkspaceProxyRow />`. We were duplicating borders and this would lead
to a `2px` border (`1px + 1px` added together). I've resolved this by
using the `divide-y` class in Tailwind so that things look more uniform.

Jaayden Halko 4e1cedf8fd chore: migrate workspace agent row styling to Tailwind (#22195) 2026-02-25 17:43:29 +00:00
Jake HowellandKayla はな 15a2bab1cd feat: migrate from <GlobalSnackbar /> to sonner (#22258)
Replaces our custom `<GlobalSnackbar />` (MUI Snackbar + event emitter)
with [`sonner`](https://github.com/emilkowalski/sonner). Deletes
`GlobalSnackbar/`, the custom event emitter infra, and migrates ~80
source files to `toast.success()` / `toast.error()` from `sonner`.

- ~47 error toasts now surface API error detail via
`getErrorDetail(error)` in the toast description, not just a generic
message. Coincides with #22229.
- Toast messages follow an `{Action} "{entity}" {result}.` format (e.g.
`User "alice" suspended successfully.`) since toasts persist across
navigation now.
- 17 uses of `toast.promise()` for loading → success → error lifecycle.
- Some toasts include action buttons for quick navigation (e.g. "View
task", "View template").
- Multiple toasts can stack and display simultaneously.

Jake Howell d2787df442 feat: add AI Bridge request logs model filter (#22230)
This pull-request implements a simple filtering logic so that we're able
to pick which model the user actually used when logs were sent to AI
Bridge.

- Add `GET /aibridge/models` API endpoint that returns distinct model
names from AI Bridge interceptions, with pagination and search support
- New `ListAIBridgeModels` SQL query using case-sensitive prefix
matching (`LIKE model || '%'`) to allow B-tree index usage
- Hand-written `ListAuthorizedAIBridgeModels` in `modelqueries.go` for
RBAC authorization filter injection
- `AIBridgeModels` search query parser in searchquery/search.go
(defaults bare terms to the `model` field)
- dbauthz wrappers, dbmetrics, and dbmock implementations for the new
query

Jake HowellandPhorcys 1dec1ec4ad fix: add getValidationErrorMessage() to getErrorDetail() (#22229)
This pull-request ensures that we render the validation errors back to
the user when the errors contain context as to why. Previously when we
attempted to we'd guide the user to simply checkout the Dev Console.
This wasn't a great approach as the user still would have to decode
this, the context is explicit now.

The error messages could use some improvement, but we make use of this
already in
[`Filter.tsx`](https://github.com/coder/coder/blob/main/site/src/components/Filter/Filter.tsx#L259)
so at-least its inline.

Jake Howell adcdbfd562 feat: implement AI Bridge client table column (#22228)
Closes #22144

Add client information column to AI Bridge request logs, showing which
coding tool initiated each request with matching icons.

- Added `Client` column to request logs table header and row, displaying
client name with icon badge
- Created `AIBridgeClientIcon` component mapping backend client
constants to their icons (Claude Code, Codex, Kilo Code, Roo Code, Zed,
Cursor, GitHub Copilot)
([ref.](https://github.com/coder/aibridge/blob/11fe0799402a652743104d047140fbeb28f02d24/bridge.go#L33-L41))
- Moved `AIBridgeModelIcon` and `AIBridgeProviderIcon` into `icons/`
subdirectory and clean up `props.className` → `className` prop
- Added new static icons: `github-copilot.svg`, `kilo-code.svg`,
`roo-code.svg` with entries in `icons.json` and `externalImages.ts`
- Sorted `externalImages.ts` map alphabetically

Kacper Sawicki 1e274063d4 feat(coderd): filter expired API tokens server-side (#22263)
## Summary

Moves expired token filtering from client-side to server-side by adding
an `include_expired` parameter to the `GetAPIKeysByLoginType` and
`GetAPIKeysByUserID` database queries. This is more efficient for large
deployments with many expired/short-lived tokens.

## Changes

- Add `include_expired` parameter to SQL queries using `OR`
short-circuit
- Add `include_expired` query parameter to `GET
/users/{user}/keys/tokens`
- Add `IncludeExpired` field to `codersdk.TokensFilter`
- Remove client-side filtering from CLI `tokens list` command
- Add `TestTokensFilterExpired` test

Fixes coder/internal#1357

blinkagent[bot]andblink-so[bot] bf076fb7ee feat: add anthropic and gemini-monochrome icons (#22270)
Adds two new icons to the icon library:

- **`anthropic.svg`** — Anthropic logo
- **`gemini-monochrome.svg`** — Gemini logo, monochrome variant

Both use `monochrome` theme handling to adapt for dark and light
backgrounds.

### Changes
- Added `anthropic.svg` and `gemini-monochrome.svg` to
`site/static/icon/`
- Registered both in `site/src/theme/icons.json` (alphabetically sorted)
- Added `monochrome` theme handling for both in
`site/src/theme/externalImages.ts`

Thomas Kosiewski b776a14b46 fix(coderd): harden OAuth2 provider security (#22194)
## Summary

Harden the OAuth2 provider with multiple security fixes addressing
`coder/security#121` (CSRF session takeover) and converge on OAuth 2.1
compliance.

### Security Fixes

| Fix | Description | Commits |
|-----|-------------|---------|
| **CSRF on `/oauth2/authorize`** | Enforce CSRF protection on the
authorize endpoint POST (consent form submission) | `ba7d646`, `b94a64e`
|
| **Clickjacking: `frame-ancestors` CSP** | Prevent consent page from
being iframed (`Content-Security-Policy: frame-ancestors 'none'` +
`X-Frame-Options: DENY`) | `597aeb2` |
| **Exact redirect URI matching** | Changed from prefix matching to full
string exact matching per OAuth 2.1 §4.1.2.1 | `73d64b1`, `93897f1` |
| **Store & verify `redirect_uri`** | Store redirect_uri with auth code
in DB, verify at token exchange matches exactly (RFC 6749 §4.1.3) |
`50569b9`, `d7ca315` |
| **Mandatory PKCE** | Require `code_challenge` at authorization (for
`response_type=code`) + unconditional `code_verifier` verification at
token exchange | `d7ca315`, `1cda1a9` |
| **Reject implicit grant** | `response_type=token` now returns
`unsupported_response_type` error page (OAuth 2.1 removes implicit flow)
| `d7ca315`, `91b8863` |

### Changes by File

**`coderd/httpmw/csrf.go`** — Extended the CSRF `ExemptFunc` to enforce
CSRF on `/oauth2/authorize` in addition to `/api` routes. The consent
form POST is now CSRF-protected to prevent cross-site authorization code
theft.

**`site/site.go`** — Added `Content-Security-Policy: frame-ancestors
'none'` and `X-Frame-Options: DENY` headers to `RenderOAuthAllowPage`
(consent page only — does not affect the SPA/global CSP used by AI
tasks).

**`coderd/httpapi/queryparams.go`** — Changed `RedirectURL` from prefix
matching (`strings.HasPrefix(v.Path, base.Path)`) to full URI exact
matching (`v.String() != base.String()`), comparing scheme, host, path,
and query.

**`coderd/oauth2provider/authorize.go`** — Added PKCE enforcement:
`code_challenge` is required when `response_type=code` (via a
conditional check, not `RequiredNotEmpty`, so `response_type=token` can
reach the explicit rejection path). `ShowAuthorizePage` (GET) validates
`response_type` before rendering and returns a 400 error page for
unsupported types. `ProcessAuthorize` (POST) stores the `redirect_uri`
with the auth code when explicitly provided.

**`coderd/oauth2provider/tokens.go`** — PKCE verification is now
unconditional (not gated on `code_challenge` being present in DB). If
the stored code has a `redirect_uri`, the token endpoint verifies it
matches exactly — mismatch returns `errBadCode` → `invalid_grant`.
Missing `code_verifier` returns `invalid_grant`.

**`codersdk/oauth2.go`** — `OAuth2ProviderResponseTypeToken` constant
and `Valid()` acceptance are **kept** so the authorize handler can parse
`response_type=token` and return the proper `unsupported_response_type`
error rather than failing at parameter validation.

**`coderd/database/migrations/000421_*`** — Added `redirect_uri text`
column to `oauth2_provider_app_codes`.

### Design Decisions

**`state` parameter remains optional** — The plan initially required
`state` via `RequiredNotEmpty`, but this was reverted in `376a753` to
avoid breaking existing clients. The `state` is still hashed and stored
when provided (via `state_hash` column), securing clients that opt in.

**`response_type=token` kept in `Valid()`** — Removing it from `Valid()`
would cause the parameter parser to reject the request before the
authorize handler can return the proper `unsupported_response_type`
error. The constant is kept for correct error handling flow.

**CSP scoped to consent page only** — `frame-ancestors 'none'` is set
only on the OAuth consent page renderer, not globally. The SPA/global
CSP was previously changed to allow framing for AI tasks
([#18102](https://github.com/coder/coder/pull/18102)); this change does
not regress that.

### Out of Scope (follow-up PRs)

- Bearer tokens in query strings (needs internal caller audit)
- Scope enforcement on OAuth2 tokens
- Rate limiting on dynamic client registration

# Plan: Harden OAuth2 Provider — Security Fixes + OAuth 2.1 Compliance

## Context & Why

Security issue `coder/security#121` reports a critical session takeover
via CSRF on the OAuth2 provider. This plan covers all remaining security
fixes from that issue **plus** convergence on OAuth 2.1 requirements.
The goal is a single PR that closes all actionable gaps.

## Current State (already committed on branch `csrf-sjx1`)

| Fix | Status | Commits |
|-----|--------|---------|
| Fix 1: CSRF on `/oauth2/authorize` | ✅ Done | `ba7d646`, `b94a64e` |
| CSRF token in consent form HTML | ✅ Done | `b94a64e` |
| `state_hash` column + storage | ✅ Done (hash stored, but state still
optional) | `9167d83`, `b94a64e` |
| Tests for CSRF + state hash | ✅ Done | `e4119b5` |

## Remaining Work

### ~~Fix 2 — Require `state` parameter~~ (DROPPED)

> **Decision:** Do not enforce `state` as required. The `state`
parameter is still hashed and stored when provided (via
`hashOAuth2State` / `state_hash` column from prior commits), but clients
are not forced to supply it. This avoids breaking existing integrations
that omit state.

**Rollback:** Remove `"state"` from the `RequiredNotEmpty` call in
`coderd/oauth2provider/authorize.go:42`:

```go
// BEFORE (current on branch)
p.RequiredNotEmpty("response_type", "client_id", "state", "code_challenge")

// AFTER
p.RequiredNotEmpty("response_type", "client_id", "code_challenge")
```

No test changes needed — tests already pass `state` voluntarily.

### Fix 4 — Exact redirect URI matching

Currently `coderd/httpapi/queryparams.go:233` uses prefix matching:

```go
// CURRENT — prefix match
if v.Host != base.Host || !strings.HasPrefix(v.Path, base.Path) {
```

OAuth 2.1 requires **exact string matching**. Change to:

```go
// AFTER — exact match (OAuth 2.1 §4.1.2.1)
if v.Host != base.Host || v.Path != base.Path {
```

**File: `coderd/httpapi/queryparams.go` — `RedirectURL` method**

Also update the error message from "must be a subset of" to "must
exactly match".

**Additionally**, store `redirect_uri` with the auth code and verify at
the token endpoint (RFC 6749 §4.1.3):

1. **New migration** (same migration file or a new `000421`): Add
`redirect_uri text` column to `oauth2_provider_app_codes`
2. **Update INSERT query** in `coderd/database/queries/oauth2.sql` to
include `redirect_uri`
3. **`coderd/oauth2provider/authorize.go`**: Store
`params.redirectURL.String()` when inserting the code
4. **`coderd/oauth2provider/tokens.go`**: After retrieving the code from
DB, verify that `redirect_uri` from the token request matches the stored
value exactly. Currently `tokens.go:103` calls `p.RedirectURL(vals,
callbackURL, "redirect_uri")` for prefix validation only — it must
compare against the stored redirect_uri from the code, not just the
app's callback URL.

<details>
<summary>Why both exact match AND store+verify?</summary>

Exact matching at the authorize endpoint prevents open redirectors
(attacker can't use a sub-path).
Storing and verifying at the token endpoint prevents code injection — an
attacker who steals a code can't exchange it with a different
redirect_uri than was originally authorized. This is required by RFC
6749 §4.1.3 and OAuth 2.1.
</details>

### Fix 7 — `frame-ancestors` CSP on consent page

The consent page can be iframed by a workspace app (same-site), which is
the attack vector. Add a `Content-Security-Policy` header to prevent
framing.

**File: `site/site.go` — `RenderOAuthAllowPage` function (~line 731)**

Before writing the response, add:

```go
func RenderOAuthAllowPage(rw http.ResponseWriter, r *http.Request, data RenderOAuthAllowData) {
    rw.Header().Set("Content-Type", "text/html; charset=utf-8")
    // Prevent the consent page from being framed to mitigate
    // clickjacking attacks (coder/security#121).
    rw.Header().Set("Content-Security-Policy", "frame-ancestors 'none'")
    rw.Header().Set("X-Frame-Options", "DENY")
    ...
```

Both headers for defense-in-depth (CSP for modern browsers,
X-Frame-Options for legacy).

### OAuth 2.1 — Mandatory PKCE

Currently PKCE is checked only when `code_challenge` was provided during
authorization (`tokens.go:258`):

```go
// CURRENT — conditional check
if dbCode.CodeChallenge.Valid && dbCode.CodeChallenge.String != "" {
    // verify PKCE
}
```

OAuth 2.1 requires PKCE for ALL authorization code flows. Change to:

**File: `coderd/oauth2provider/authorize.go`** — Add `"code_challenge"`
to required params:

```go
p.RequiredNotEmpty("response_type", "client_id", "code_challenge")
```

**File: `coderd/oauth2provider/tokens.go:257-265`** — Make PKCE
verification unconditional:

```go
// AFTER — PKCE always required (OAuth 2.1)
if req.CodeVerifier == "" {
    return codersdk.OAuth2TokenResponse{}, errInvalidPKCE
}
if !dbCode.CodeChallenge.Valid || dbCode.CodeChallenge.String == "" {
    // Code was issued without a challenge — should not happen
    // with the authorize endpoint enforcement, but defend in
    // depth.
    return codersdk.OAuth2TokenResponse{}, errInvalidPKCE
}
if !VerifyPKCE(dbCode.CodeChallenge.String, req.CodeVerifier) {
    return codersdk.OAuth2TokenResponse{}, errInvalidPKCE
}
```

**File: `codersdk/oauth2.go`** — Remove
`OAuth2ProviderResponseTypeToken` from the enum or reject it explicitly
in the authorize handler. Currently it's defined at line 216 but the
handler ignores `response_type` and always issues a code. We should
either:
- (a) Remove the `"token"` variant from the enum and reject it with
`unsupported_response_type`, OR
- (b) Add an explicit check in `ProcessAuthorize` that rejects
`response_type=token`

Option (b) is simpler and more backwards-compatible:

```go
// In ProcessAuthorize, after extracting params:
if params.responseType != codersdk.OAuth2ProviderResponseTypeCode {
    httpapi.WriteOAuth2Error(ctx, rw, http.StatusBadRequest,
        codersdk.OAuth2ErrorCodeUnsupportedResponseType,
        "Only response_type=code is supported")
    return
}
```

### OAuth 2.1 — Bearer tokens in query strings

`coderd/httpmw/apikey.go:743` accepts `access_token` from URL query
parameters. OAuth 2.1 prohibits this. However, this may be used
internally (e.g., workspace apps, DERP). Need to audit callers before
removing.

**Approach:** This is a larger change with potential breakage. Mark as a
**separate follow-up issue** rather than including in this PR. Document
the finding.

### OAuth 2.1 — Removed flows

✅ **Already compliant.** `tokens.go` only supports `authorization_code`
and `refresh_token` grant types. The implicit grant
(`response_type=token`) will be explicitly rejected per the PKCE section
above.

### OAuth 2.1 — Refresh token rotation

✅ **Already compliant.** `tokens.go:442` deletes the old API key when a
refresh token is used.

## Migration Plan

All DB changes can go in a single new migration (or extend 000420 if the
branch is rebased before merge). Columns to add:
- `redirect_uri text` on `oauth2_provider_app_codes`

The `state_hash` column is already added by migration 000420.

## Implementation Order

1. **Fix 7** — CSP headers on consent page (isolated, no deps)
2. ~~**Fix 2** — Require `state` parameter~~ (DROPPED — state stays
optional)
3. **Fix 4** — Exact redirect URI matching + store/verify redirect_uri
4. **PKCE mandatory** — Require `code_challenge` + reject
`response_type=token`
5. **Rollback** — Remove `"state"` from `RequiredNotEmpty` in
`authorize.go`
6. **Tests** — Update/add tests for all changes
7. **`make gen`** after DB changes

## Out of Scope (separate PRs)

- Bearer tokens in query strings (needs internal caller audit)
- Scope enforcement on OAuth2 tokens
- Rate limiting / quota on dynamic client registration

Jeremy RuppelandClaude Sonnet 4.5 de4ff78cd1 fix(site): show when secret deployment options are configured (#22151)
Previously, when secret deployment options like CODER_OIDC_CLIENT_SECRET
were populated, the API correctly returned the "secret": "true"
annotation, but the UI did not indicate that these secrets were
configured. The UI would show "Not set" regardless of whether the secret
was set or not.

Now, the UI checks both the secret annotation and the value_source
field. When a secret is configured (value_source is set), it displays
"Set" to indicate the secret is populated. When a secret is not
configured, it displays "Not set".

Fixes #18913

Jake Howell 051ed34580 feat: convert soft_limit to limit (#22048)
In relation to
[`internal#1281`](https://github.com/coder/internal/issues/1281)

Remove the `soft_limit` field from the `Feature` type and simplify
license limit handling. This change:

- Removes the `soft_limit` field from the API and SDK
- Uses the soft limit value as the single `limit` value in the UI and
API
- Simplifies warning logic to only show warnings when the limit is
exceeded
- Updates tests to reflect the new behavior
- Updates the UI to use the single limit value for display

Jake Howell 203899718f feat: remove agent workspaces limit (#21998)
In relation to
[`internal#1281`](https://github.com/coder/internal/issues/1281)

Managed agent workspace build limits are now advisory only. Breaching
the limit no longer blocks workspace creation — it only surfaces a
warning.

- Removed hard-limit enforcement in `checkAIBuildUsage` so AI task
builds are always permitted regardless of managed agent count.
- Updated the license warning to remove "Further managed agent builds
will be blocked." verbiage.
- Updated tests to assert builds succeed beyond the limit instead of
failing.
- Removed the "Limit" display from the `ManagedAgentsConsumption`
progress bar — the bar is now relative to the included allowance (soft
limit) only, and turns orange when usage exceeds it.

Bonus:

- De-MUI'd `LicenseBannerView` — replaced Emotion CSS and MUI `Link`
with Tailwind classes.
- Added `highlight-orange` color token to the Tailwind theme.
