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