CVE-2026-111667 Details
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.
A missing authorization vulnerability has been identified in the REBUILD low-code platform, affecting versions through 4.5.0. The issue resides in the TaskCommentController's commentList method, which handles the /project/comments/list endpoint. This vulnerability allows authenticated low-privileged users to access task comments in private projects without proper membership verification. By supplying a task ID from a private project, attackers can retrieve comment content and attachment references, bypassing project membership checks.
The vulnerability can be addressed by adding a membership check to the commentList method, similar to the checks implemented in other task read handlers. This will prevent non-members from accessing comments in private projects.
