As published by the source; long descriptions are shortened.

Finding Location: core/src/client/graphql.ts:66-80 The gql template tag function warned about interpolated values containing GraphQL metacharacters ({}():) but still concatenated them into the query string, enabling potential GraphQL injection. Status Fixed in v0.2.136 — The gql function now throws an error when metacharacters are detected in interpolated values, forcing developers to use the variables parameter.

# Patch Next advisory brief: GHSA-5c7w-4wm3-85vw

Advisory: @asymmetric-effort/specifyjs: GraphQL gql tag allows metacharacter injection
IDs: GHSA-5c7w-4wm3-85vw
Record: https://patchnext.com/advisories/ghsa-5c7w-4wm3-85vw (revision 3, source checked 26 Oct 2026, 12:56 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @asymmetric-effort/specifyjs 0.2.136. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @asymmetric-effort/specifyjs: affected < 0.2.136; fixed in 0.2.136

## Suggested inspection (read-only)
- `npm ls @asymmetric-effort/specifyjs --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @asymmetric-effort/specifyjs.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
