Content data (frontmatter, YAML, JSON) was spread into components and bound as links, so a previewed PR could inject attributes and script URLs.

  • sanitizeData() from comark/utils now sanitizes every file's data, after the other plugins: YAML/JSON not covered by security()
  • script URLs are also dropped under any key, as templates bind demo or website as links
  • one SECURITY_OPTIONS drives both security() and the custom data sanitizer plugin
  • content reaches components through pickLink() / pickLinks() / pickFeature() / pickUser() / pickAvatar() instead of v-bind spreads, so only allowlisted keys reach the DOM

Uses the comarkdown/comark#486 preview packages for now: switch to the release before merging.

📝 Walkthrough

The content parser cache version changes from v7 to v8. A new sanitizer removes unsafe keys and values from parsed file data. The shared content plugin setup configures the sanitizer with the blocked tags. Unit tests cover removal behavior, warnings, and plugin ordering.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 59004

The PR hardens content rendering, but it temporarily relaxes pnpm's guard against exotic dependency sources and depends on preview comark packages. Switch to the released comark packages and remove the opt-out before or shortly after merging.

pnpm 12 blockExoticSubdeps documentation exotic subdependencies direct tarball Git dependencies

💡 Result:

For **pnpm 12**, `blockExoticSubdeps` blocks **transitive dependencies** from using exotic sources such as Git repositories and direct tarball URLs. Direct dependencies declared in the root `package.json` may still use those sources. ([github.com](https://github.com/pnpm/pnpm.io/blob/main/versioned_docs/version-10.x/settings.md))

```yaml
# pnpm-workspace.yaml
blockExoticSubdeps: true
```

**Version note:** The settings page I found documents this option as added in pnpm v10.26.0; it is a version 10 page, not pnpm 12-specific documentation. The current pnpm security guide describes the same behavior, but doesn’t specify a pnpm 12 version. ([github.com](https://github.com/pnpm/pnpm.io/blob/main/versioned_docs/version-10.x/settings.md))

🌐 Web query:

site:pnpm.io/settings blockExoticSubdeps pnpm 12

💡 Result:

For **pnpm 12**, `blockExoticSubdeps` blocks **transitive dependencies** from resolving to exotic sources such as Git repositories or direct tarball URLs. The current pnpm site says it’s enabled by default. ([pnpm.io](https://pnpm.io/supply-chain-security?utm_source=openai))

Set it in `pnpm-workspace.yaml`:

```yaml
blockExoticSubdeps: true
```

The pnpm 12.0 release notes confirm pnpm 12 is a stable release, but the search results don’t show a version-specific settings entry for this option; the behavior above is from the current pnpm documentation.

Remove blockExoticSubdeps: false when the comark release is available.

pnpm 12.11.2 enables this guard by default. The temporary setting is currently required because @comark/nuxt resolves transitive @comark/vue and comark dependencies from pkg.pr.new tarballs. Keep this opt-out only for the temporary comark pins, then remove it when comarkdown/comark#486 ships.
