Description
NVD
ONEARMY community-platform before 2.165.2 contains an insecure direct object reference vulnerability that allows authenticated users to mark other users' notifications as read via POST /api/notifications/:id/read. Attackers can iterate sequential notification IDs to suppress unread indicators of users in the same tenant, causing them to miss replies, comments and new-content notices.
