Description
Insufficient Verification of Data Authenticity vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.1. A missing authorization check in the external-login email binding flow allows unauthenticated attackers to take over arbitrary user accounts by tricking victims into clicking a crafted confirmation link. Users are recommended to upgrade to version 2.0.2, which fixes the issue.
