CVE-2026-64944— Apache Answer: Stored XSS via unsanitized HTML in imported question content

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“网页生成过程中输入未正确中和”（跨站脚本攻击，XSS）漏洞。 该问题影响 Apache Answer 2.0.2 及以下版本。 在导入过程中，系统会将导入的问题正文以原始 HTML 形式存储，而未经过常规的 Markdown 转 HTML 的清理流程。因此，若导入的数据源中嵌入了由攻击者控制的 HTML 代码，这些代码将被持久化保存，并渲染给所有用户（包括特权用户），从而构成存储型跨站脚本攻击（Stored XSS）。 建议用户升级至已修复此问题的 2.0.3 版本。

Vulnerability Title
Apache Answer: Stored XSS via unsanitized HTML in imported question content
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.2. The importer stores imported question bodies as raw HTML without passing them through the normal Markdown-to-HTML sanitization path, so attacker-controlled HTML embedded in an imported data source is persisted and rendered to all viewers (including privileged users) as stored XSS. Users are recommended to upgrade to version 2.0.3, which fixes the issue.
