First of two PRs.
Notification title and body templates are Markdown authored by Coder,
but the label values interpolated into them are user-controlled and were
substituted through `text/template`, which does no escaping. Those
values arrive from user profile fields and from OIDC/GitHub name claims.
This PR:
- Neutralizes Markdown structure in label, data, and `UserName` values
before they reach the template. Applied in `notifier.prepare`, so
already-queued messages are covered and the stored payload keeps its
original values for webhook consumers. Nested `.Data` map keys are
escaped too: one shipped template prints a key, and those keys are
Terraform resource addresses.
- Narrows the notification Markdown grammar to what templates actually
use. `CommonExtensions` enabled Tables, DefinitionLists and MathJax,
each openable from a value and used by no template. Autolink stays off
so a URL in a value cannot become an anchor.
- Enables `html.Safelink`, restricting generated hrefs to safe schemes,
and guards the panic it exposes: `parser.IsSafeURL` slices a destination
before bounds-checking it, so `[docs]()` crashed both renderers.
- Folds line breaks out of the `Subject:` header and encodes it, fixing
a pre-existing RFC 2047 violation for non-ASCII subjects, a forged
encoded-word that let a value choose the displayed subject, and headers
running past RFC 5322's 998-octet line limit.
Escaping is narrow on purpose, split by where each character carries
meaning:
- `` \[]()!<` `` everywhere. Backtick is in this group because a fenced
block's info string is an HTML sink: gomarkdown writes it into
`class="language-..."` unescaped, and `SkipHTML` does not apply to a
`CodeBlock` node, so a value that closes the attribute and the tag
injects live markup.
- `#-+.>|` only in leading position, so values like `bobby-workspace`
and `1.5` are untouched.
- `=`, `~` and `:` are not escapable by both renderers, so the preceding
line break is folded instead. `:` opens a definition list and a GFM
table delimiter row that escaping `|` cannot reach. A value's *first*
line has no preceding break to fold, so a real tilde fence or `===`
underline is escaped there instead, accepting a visible backslash: an
unterminated `~~~` at the start of a title otherwise renders the
Subject, `<title>` and heading empty.
- Leading indentation is truncated to three spaces. Four open an
indented code block and a space has no escape.
- Emphasis characters are left alone. Escaping `_` corrupts label values
such as `user_override` that body templates compare with `eq`, which
silently drops content from the rendered email.
One golden file changes: the resource replacements `body_markdown` now
reads `docker_container\[0\]`, from the map-key escaping above. Every
other golden is byte-identical.
**One known residual**, pinned by a test that fails if it closes:
CommonMark does not process escapes inside a code span, so where a
template wraps a value in one, as the workspace out-of-disk body does,
the escaper's own backslashes reach the reader. That depends on where
the value lands rather than what it contains, which a pre-render escaper
cannot see. This narrows the class rather than closing it.
**#28397 completes the fix and is stacked on this branch. This PR should
not merge without it.**
Escaping here cannot reach the SMTP HTML template's sinks, by design
rather than by oversight: the subject is produced by
`PlaintextFromMarkdown`, which strips exactly the backslashes added
here, and `html.gotmpl` then interpolated the result through
`text/template`. On this branch alone, a label value still reaches the
Subject, `<title>` and `<h1>` as live markup. #28397 escapes at those
sinks with `| html`, which is the only place the information needed to
escape correctly exists.
This reverts commit 07f79af65b ("fix:
markdown rendering improvements").
The revert was applied cleanly with `git revert` and restores the
notification rendering pipeline to its prior state, including:
- `coderd/notifications/dispatch/smtp.go` and `smtp/html.gotmpl`
- `coderd/notifications/notifier.go` and `render/gotmpl.go`
- Removal of `coderd/notifications/render/sanitize_test.go` and
`smtp_internal_test.go` additions
- Regenerated SMTP golden templates under
`coderd/notifications/testdata/`
`go build ./coderd/notifications/...` passes on the reverted tree.

Improvements to markdown rendering in notification emails:
- More consistent escaping of values interpolated into notification templates
- Stricter link handling in the notification email renderer, scoped to the notification rendering path
- HTML escaping of values interpolated into the outer email template
- Expanded unit and end-to-end coverage of the notification rendering pipeline
- `make gen` run to regenerate golden files for SMTP and webhook notification templates
Migrate `wg.Add(1); go func() { defer wg.Done(); ... }()` to
`wg.Go(func() { ... })` in tests.
Where the prior pattern passed the loop variable explicitly via a
closure parameter (`go func(id int) { ... }(i)`), drop the parameter and
reference the loop variable directly. Per-iteration loop variables since
Go 1.22 make this safe.
## Description
When configuring a From address with a display name (e.g., `Coder System
<system@coder.com>`), the SMTP `MAIL FROM` command was incorrectly
receiving the full address string instead of just the bare email
address, causing `501 Invalid MAIL argument` errors on some SMTP
servers.
## Changes
- Updated `validateFromAddr` to return both:
- `envelopeFrom`: bare email for SMTP `MAIL FROM` command (RFC 5321)
- `headerFrom`: original address with display name for email header (RFC
5322)
Fixes#20727
Fixes all our Go file imports to match the preferred spec that we've _mostly_ been using. For example:
```
import (
"context"
"time"
"github.com/prometheus/client_golang/prometheus"
"golang.org/x/xerrors"
"gopkg.in/natefinch/lumberjack.v2"
"cdr.dev/slog/v3"
"github.com/coder/coder/v2/codersdk/agentsdk"
"github.com/coder/serpent"
)
```
3 groups: standard library, 3rd partly libs, Coder libs.
This PR makes the change across the codebase. The PR in the stack above modifies our formatting to maintain this state of affairs, and is a separate PR so it's possible to review that one in detail.
Upgrades to slog v3 which includes a small, but backward incompatible API change to the acceptible call arguments when logging. This change allows us to verify via compile time type checking that arguments are correct and won't cause a panic, as was possible in slog v1, which this replaces (v2 was tagged but never used in coder/coder).
It also updates dependencies that also use slog and were updated.
I've left the `aibridge` dependency as a commit SHA, under the assumption that the team there (cc @pawbana @dannykopping ) will tag and update the dependency soon and on their own schedule.
Other dependencies, I pushed new tags.
- Update go.mod to use Go 1.24.1
- Update GitHub Actions setup-go action to use Go 1.24.1
- Fix linting issues with golangci-lint by:
- Updating to golangci-lint v1.57.1 (more compatible with Go 1.24.1)

This PR aims to allow clients to use different format for the title and
content of inbox notifications - on the watch endpoint.
This solution will help to have it working and formatted differently on
VSCode, WebUI ...
[Related to this issue](https://github.com/coder/internal/issues/523)
This PR aimes to [fix this
issue](https://github.com/coder/internal/issues/448) -
The main idea is to remove greetings from templates stored in the DB -
and instead push it into the template for require methods - for now
SMTP.
This PR is part of the inbox notifications topic, and rely on previous
PRs merged - it adds :
- Endpoints to :
- WS : watch new inbox notifications
- REST : list inbox notifications
- REST : update the read status of a notification
Also, this PR acts as a follow-up PR from previous work and :
- fix DB query issues
- fix DBMem logic to match DB
This PR is [resolving the dispatch part of Coder
Inbocx](https://github.com/coder/internal/issues/403).
Since the DB layer has been merged - we now want to insert notifications
into Coder Inbox in parallel of the other delivery target.
To do so, we push two messages instead of one using the `Enqueue`
method.
- Adds `testutil.GoleakOptions` and consolidates existing options to
this location
- Pre-emptively adds required ignore for this Dependabot PR to pass CI
https://github.com/coder/coder/pull/16066
Resolves https://github.com/coder/coder/issues/15513
Disables notifications when both `$CODER_NOTIFICATIONS_WEBHOOK_ENDPOINT` and `$CODER_EMAIL_SMARTHOST` are unset.
Breaking change: `$CODER_EMAIL_SMARTHOST` is no longer set by default as `localhost:587`, meaning any deployments that make use of this default value will need to add it back.

This PR aims to close#14253
We keep the default behavior using the Coder logo if there's no logo
set.
Otherwise we want to use the logo based on the URL set in appearance.
