**Short answer:** pnpm **11.1.1 is affected** by GHSA-54hh-g5mx-jqcp. The advisory affects pnpm `>=11.0.0 <11.4.0`; it is fixed in **11.4.0+** (and **10.34.0+** on the 10.x line). ([github.com](https://github.com/pnpm/pnpm/security/advisories/GHSA-54hh-g5mx-jqcp?utm_source=openai))

- **On affected versions:** with a non-frozen `pnpm install`, if the registry serves different tarball content for a version whose integrity is in the lockfile, pnpm can report the mismatch, re-resolve, replace the lockfile integrity with the registry’s new value, install that content, and exit successfully. `--frozen-lockfile` fails instead. ([github.com](https://github.com/pnpm/pnpm/security/advisories/GHSA-54hh-g5mx-jqcp?utm_source=openai))
- **`trustPolicy: no-downgrade` is not a fix for this advisory.** It checks whether a package’s *trust evidence* has weakened compared with earlier-published versions; it does not make the lockfile’s tarball integrity authoritative. That distinction is an inference from the separate documented behaviors. ([github.com](https://github.com/pnpm/pnpm.io/blob/main/versioned_docs/version-10.x/settings.md?utm_source=openai))
- **Recommended:** upgrade to pnpm **11.4.0 or later**. The 11.4 release makes integrity mismatches hard failures by default; `--update-checksums` is the explicit opt-in for updating checksums. ([pnpm.io](https://pnpm.io/blog/releases/11.4?trk=article-ssr-frontend-pulse_x-social-details_comments-action_comment-text&utm_source=openai))

The advisory establishes the vulnerable behavior and affected range, but does **not** establish the exact internals or guarantees of `--update-checksums` in **11.1.1**—that version predates the documented fix.

Upgrade the project’s pnpm version to 11.4.0 or later before retaining the
[email protected] exception in the workspace configuration; update the packageManager
setting to enforce the supported version.

Review comment at @package.json around lines 8 - 10:
Update the pnpm declarations in all five manifests to require pnpm 11.11.0 or
later: set each packageManager pin to 11.11.0, and update the root engines.pnpm
minimum to 11.11.0.
