Name of the Vulnerable Software and Affected Versions Plane versions prior to 1.4.0
Description The issue-relation endpoint accepts issue UUIDs in the request body without validating that they belong to the caller's workspace. This allows an authenticated user to create relations linking their own issues to issues in any other workspace on the instance, which results in the leakage of issue metadata through activity events.
Recommendations Update to version 1.4.0.
