Technical details

The vulnerability is an incorrect authorization flaw in the PATCH /api/v1/users/{user} endpoint that fails to prevent restricted API tokens (limited to manage_users and edit_users permissions) from modifying the owner's own password, email, and two-factor authentication settings. An authenticated attacker with a restricted token can escalate to full owner privileges and access all account data. The fix restricts credential changes via API to prevent token holders from modifying their own sensitive attributes.
