Description

Summary

A low-privileged authenticated user can call assets/image-editor with the ID of a private asset they cannot view and still receive editor response data, including focalPoint.

The endpoint returns private editing metadata without per-asset authorization validation.

Root-cause analysis:

  1. actionImageEditor() accepts assetId from the request body.
  2. The asset is loaded, and the focal-point data is read.
  3. Response returns html and focalPoint.
  4. No explicit authorization check is applied before the response.

Impact

Affected deployments:

  • Craft sites where asset edit metadata should remain restricted to authorized users.

Security consequence:

  • Unauthorized users can extract private editor metadata and related editor context for inaccessible assets.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for craftcms/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update craftcms/cms to 5.9.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vgjg-248p-rfm2 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-vgjg-248p-rfm2 can be triaged on real exposure rather than presence alone.

Tailored to GHSA-vgjg-248p-rfm2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
