CVE-2026-111346
ZenTao PMS through 22.6 contains an authorization bypass vulnerability in action::editComment that allows authenticated users to read and overwrite other users' comments by supplying an arbitrary actionID.
Does this matter?
Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
Description
ZenTao PMS through 22.6 contains an authorization bypass vulnerability in action::editComment that allows authenticated users to read and overwrite other users' comments by supplying an arbitrary actionID. Attackers can iterate sequential action ids to modify comments on bugs, stories, tasks, and documents in products and projects they cannot access, and view targeted comment content and attachments.
