CVE-2026-116018
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.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
Description
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.
