Apache Answer 2.0.2 Stored XSS via Importer
CVE-2026-64944 Published on October 19, 2026
Apache Answer: Stored XSS via unsanitized HTML in imported question content
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.
