Original description
The description as published by the source.
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.
