Summary
Incorrect authorization vulnerability in SkillHub before version 0.2.22 in AccountMergeService and AccountMergeController. Allows authenticated attackers to take over other accounts by abusing the merge flow. Attackers can call the merge initiate endpoint with a target username or OAuth identity, receive the verification token directly, and confirm the merge to inherit the victim's API tokens, roles and namespace ownership.
Risk Assessment
An attacker could take over other users' accounts, potentially leading to data theft, confidentiality and integrity breaches.
Recommendation
Update SkillHub to version 0.2.22 or later. Additionally, restrict access to account merge functionality and monitor activity related to this process.
