Subject: CVE-2026-64945: Apache Answer: Incorrect permission mapping allows
users with only the unpin permission to hide/show questions
Severity: low
Affected versions:
- Apache Answer through 2.0.2
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.
