Impact

External Security Researchers have identified a privilege escalation critical vulnerability. The vulnerability allows
a normal user to gain administrator account privileges by making an API call to modify the email address of a specific user. Subsequently they can reset the password for that email address and gain access to that account. The Harbor API did not enforce the proper permissions and scope on the API request to modify the email address. The vulnerability was immediately fixed by the Harbor team and all supported versions were patched.
