CVE-2026-111667
REBUILD through 4.5.0 contains a missing authorization vulnerability in TaskCommentController.commentList that allows authenticated low-privileged users to read task comments without project membership checks.
Does this matter?
Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.
Description
REBUILD through 4.5.0 contains a missing authorization vulnerability in TaskCommentController.commentList that allows authenticated low-privileged users to read task comments without project membership checks. Attackers can supply the id of a task in a private project to the /project/comments/list endpoint to retrieve its comment content and attachment references.
