Subject: CVE-2026-34031: Apache Answer: The custom avatar was not properly
 validated 

Severity: moderate 

Affected versions:

- Apache Answer through 2.0.0

Description:

Unrestricted 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.
