# CVE-2026-64945: Apache Answer: Incorrect permission mapping allows users with only the unpin permission to hide/show questions

Status: published. Published: 2026-10-19. Updated: 2026-11-03.

A vulnerability in Apache Answer.



This issue affects Apache Answer: through 2.0.2.

The question operation controller gates hide/show operations on the wrong permission check result (the unpin permission instead of the hide permission), so in custom role configurations that separate these permissions, a user granted only question.unpin can hide or restore questions without holding question.hide or question.show.


Users are recommended to upgrade to version 2.0.3, which fixes the issue.
