Description

Incorrect implementation of authentication algorithm vulnerability in Apache Answer.

This issue affects Apache Answer: through 2.0.2.

A flaw in the User Center login integration can cause a newly created external user session to omit its external identity, allowing subsequent requests to bypass central account suspension or deletion checks until the session expires or is revoked.

Users are recommended to upgrade to version 2.0.3, which fixes the issue.
