Detailed vulnerability description
The vulnerability allows a remote user to bypass channel-level access control and disclose protected content.
The vulnerability exists due to improper access control in the setPassword.json.php endpoint of the CustomizeUser plugin when processing administrator-supplied ProfilePassword values for another user's channel. A remote privileged user can submit a non-numeric password for another user's channel to bypass channel-level access control and disclose protected content.
