Closes the 26 open Dependabot alerts on main (13 high, 11 moderate, 2 low), plus browserslist and postcss-selector-parser, which pnpm audit flags but GitHub had not surfaced yet — 29 advisories in total.

Why Dependabot never fixed these

Two independent reasons, both addressed here:

  1. Security updates were never enabled. .github/dependabot.yml only configured version updates. Dependabot security updates — the ones that open a PR in response to an alert — are a repository setting, not config. They still need turning on under Settings → Code security → Dependabot security updates (see the follow-up below).

  2. Every affected package is transitive. Not one appears in package.json. Dependabot only bumps a nested dependency when some parent release requires the fixed version; when the fix needs an override it gives up silently. That covers this entire list, so pnpm.overrides is the mechanism that actually applies.

Where they come from:

Source Advisory packages
shadcn@modelcontextprotocol/sdk fast-uri, hono, ip-address, qs, js-yaml, undici
react-email socket.io-parser, brace-expansion
next / @tailwindcss/postcss / vite nanoid, postcss, postcss-selector-parser, browserslist

Changes

Every patched version lands within the current major, so there are no breaking upgrades:

Package Before After Fixes
brace-expansion 5.0.7 5.0.9 2 high
browserslist 4.28.6 4.28.9 2 high
fast-uri 3.1.4 3.1.7 5 high
hono 4.12.31 4.13.7 3 moderate, 1 low
ip-address 10.2.0 10.7.0 1 high, 2 moderate
js-yaml 4.3.0 4.3.2 1 high
nanoid 3.3.12 3.3.18 2 high
postcss 8.5.19 8.5.28 1 moderate
postcss-selector-parser 7.1.x 7.1.6 1 low
qs 6.15.2 6.16.0 2 moderate
socket.io-parser 4.2.6 4.2.7 1 high
undici 7.28.0 7.29.1 1 high, 4 moderate

Target versions were taken from each advisory's own patched_versions range via pnpm audit --json, not from "whatever is latest".

.github/dependabot.yml is also reworked: it now documents that security updates are a separate repo setting, adds the github-actions ecosystem, and groups routine updates (next, react, dev-deps, prod minor/patch) to cut PR noise.

Verification

  • pnpm auditNo known vulnerabilities found (was 29)
  • pnpm run check → clean, 271 files
  • pnpm test247 passed (34 files)
  • pnpm build✓ Compiled successfully in 53s

Notes for the reviewer

  • shadcn is kept deliberately. It looks like an unused scaffolding CLI, but src/app/globals.css:3 does @import "shadcn/tailwind.css", which resolves through the package's exports map to dist/tailwind.css. It is a real build dependency and removing it breaks the CSS build. It is the largest single source of advisories here, so this is worth knowing before anyone tries to prune it.
  • Build prerender caveat: a full pnpm build needs valid Spree credentials. With a dummy key it fails at prerender with Valid API key required; that failure reproduces identically on main, so it is unrelated to this change. The compile and CSS stages — the parts these overrides could plausibly affect — complete successfully.
  • Overrides are a stopgap. Each one should be dropped once the parent package ships a release carrying the fix on its own; the config comment says so.

Follow-up required (not doable from a PR)

Enable Settings → Code security → Dependabot security updates. Without it, future advisories will keep being reported and never auto-fixed — which is how this backlog accumulated.

Summary by CodeRabbit

  • Chores
    • Improved automated dependency update management by grouping related updates and supporting GitHub Actions updates.
    • Updated pinned versions for several transitive dependencies to improve compatibility and maintain reliable application behavior.
    • Refined dependency version handling to make routine updates more consistent and manageable.

Resolves the 29 open Dependabot advisories (25 alerts on GitHub, plus
browserslist and postcss-selector-parser which had not been surfaced yet).

Every affected package is a transitive dependency — none appear in
package.json — so Dependabot could not bump them on its own: a security
update only lands when a parent release requires the fixed version, and no
parent has shipped one. Pinning them through pnpm.overrides is the fix that
actually applies.

All patched versions land within the current major, so no breaking upgrades:

  brace-expansion          5.0.7  -> 5.0.9    (2 high)
  browserslist             4.28.6 -> 4.28.9   (2 high)
  fast-uri                 3.1.4  -> 3.1.7    (5 high)
  hono                     4.12.31-> 4.13.7   (3 moderate, 1 low)
  ip-address               10.2.0 -> 10.7.0   (1 high, 2 moderate)
  js-yaml                  4.3.0  -> 4.3.2    (1 high)
  nanoid                   3.3.12 -> 3.3.18   (2 high)
  postcss                  8.5.19 -> 8.5.28   (1 moderate)
  postcss-selector-parser  7.1.x  -> 7.1.6    (1 low)
  qs                       6.15.2 -> 6.16.0   (2 moderate)
  socket.io-parser         4.2.6  -> 4.2.7    (1 high)
  undici                   7.28.0 -> 7.29.1   (1 high, 4 moderate)

Also reworks .github/dependabot.yml, which only configured version updates.
Security updates are a repository setting rather than config, so the file now
says so explicitly; adds the github-actions ecosystem and groups routine
updates to cut PR noise.

`pnpm audit` now reports no known vulnerabilities. Biome check clean,
247 tests pass, production build compiles successfully.

Walkthrough

Dependabot now groups npm and GitHub Actions updates. The repository also adds and updates pnpm.overrides entries for transitive dependencies.

Changes

Dependency automation

Layer / File(s) Summary
Dependabot update policy
.github/dependabot.yml
Adds npm update limits, versioning strategy, dependency groups, and a weekly GitHub Actions update group.
Transitive dependency overrides
package.json
Adds pinned versions for transitive dependencies and updates the postcss override.

Merge Risk: 🔵 Low · up to 07084

This change expands dependency update grouping and transitive security pins. The security-update note could mislead maintainers about supported Dependabot configuration, but it does not affect current runtime behavior.

Poem

A rabbit sorts the update queue
Grouped leaves hop in batches of two
Action trails shine bright and clear
New pins keep dependencies near
The burrow builds with less ado

Comment thread package.json Outdated
Cursor Bugbot: the unscoped `postcss-selector-parser` override also replaced
the `6.0.10` that `@tailwindcss/typography@0.5.20` exact-pins, forcing a major
bump on a package that was never affected. The advisory covers only
`>=7.1.0 <7.1.3`, and the sole vulnerable path was `.>shadcn>...@7.1.1` — so
the override is now scoped to `shadcn>postcss-selector-parser`, leaving
typography on its pinned 6.0.10.

`prose` is used in production (ProductDetails, policy pages), so the generated
CSS was compared directly: parser 6.0.10 and 7.1.6 emit byte-identical output
(107462 bytes, same ::marker/::before/::after rules). The predicted breakage
did not reproduce, but scoping is still correct and costs nothing.

CodeRabbit: the "security updates are a repository setting, not config"
wording was too broad — dependabot.yml can configure security-update PRs via
a group with `applies-to: security-updates`. Reworded to separate enabling
(repo settings) from configuring (this file), and added that group so security
alerts arrive as one PR instead of one per alert.

pnpm audit still reports no known vulnerabilities. Biome clean, 247 tests
pass, production build compiles.
