Name of the Vulnerable Software and Affected Versions Memos versions prior to 0.27.0

Description Authenticated users can view activity records of all users due to missing authorization in the ActivityService ListActivities and GetActivity API endpoints. Low-privileged attackers can enumerate sequential activity IDs to retrieve creator IDs, timestamps, and memo-comment references, which may include activity related to private memos of other users.

Recommendations Update to version 0.27.0 or later. Restrict access to the ListActivities and GetActivity API endpoints to minimize the risk of unauthorized data exposure.
