CVE-2026-54050 sakaiproject CVE debrief

Who should care

Defenders responsible for Sakai CLE deployments, particularly those using versions prior to 23.5, 25.3, or 26.0, should assess exposure and apply patches to prevent unauthorized profile modifications.

Why it matters

CVE-2026-54050 is a medium-severity vulnerability in Sakai CLE that allows authenticated users to delete others' profile images and recordings without ownership checks, disrupting workflows and requiring prompt patching.

• Disruption of workflows relying on profile images and pronunciation recordings.
• Potential for repeated removal of profile identity artifacts, including administrator and instructor images.
• Need for verification of affected versions and exposure in Sakai CLE deployments.
• Priority for applying patches to prevent unauthorized profile modifications.

Technical summary

The Sakai CLE has a vulnerability in the DELETE /api/users/{userId}/profile/image and DELETE /api/users/{userId}/profile/pronunciation endpoints. An authenticated user can delete another user's profile image and pronunciation recording without verifying ownership, disrupting workflows that rely on these artifacts. The issue is fixed in versions 23.5, 25.3, and 26.0. This vulnerability allows attackers to repeatedly remove profile identity artifacts, including administrator and instructor images, which can disrupt critical workflows. Successful exploitation requires authenticated access but does not need additional privileges.

Defensive priority

Defenders should prioritize verifying exposure, assessing affected deployments, and applying patches to prevent unauthorized profile modifications.

Recommended defensive actions

• Verify exposure by checking if the Sakai CLE deployment is using an affected version (prior to 23.5, 25.3, or 26.0).
• Assess which users have access to the DELETE /api/users/{userId}/profile/image and DELETE /api/users/{userId}/profile/pronunciation endpoints.
• Apply patches to upgrade to a fixed version (23.5, 25.3, or 26.0) to prevent unauthorized profile modifications.
• Monitor for suspicious activity related to profile image and pronunciation recording deletions.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
