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

Quick assessment

Affected
Apache Software Foundation Apache Answer
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Answer 存在一个安全漏洞。 该漏洞影响 Apache Answer 2.0.2 及之前的所有版本。 问题在于：问题操作控制器在控制“隐藏/显示”操作时，错误地依据了“取消置顶”权限的校验结果，而非正确的“隐藏”权限。因此，在自定义角色配置中若将“取消置顶”与“隐藏/显示”权限分离，则仅被授予 权限的用户，即可绕过 或 权限限制，擅自隐藏或恢复问题。 建议用户升级至已修复该问题的 2.0.3 版本。

Vulnerability Title
Apache Answer: Incorrect permission mapping allows users with only the unpin permission to hide/show questions
Source: CVE Program / CVE List V5
Vulnerability 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.
