Summary
Apache Answer: Unauthenticated OAuth Email-Binding Account Takeover via Existing User Confirmation Flow
Details

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.
