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.
