CVE-2026-34031
MEDIUM 6.5Unrestricted Upload of File with Dangerous Type vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.0. The server did not sufficiently validate user-supplied image URLs, allowing arbitrary external content to be embedded as profile images, which could expose users to unintended external requests and tracking by third-party servers. Users are recommended to upgrade to version 2.0.1, which fixes the issue.
No known exploitation, public exploit, or elevated probability at this time. Track for changes.
