Summary

Apache Answer has an Unrestricted Upload of File with Dangerous Type vulnerability

Details

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.

Severity

6.5 (Medium)
