What it is

SkillHub before 0.2.22 contains an incorrect authorization vulnerability in AccountMergeService and AccountMergeController that 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.
