Technical details
The vulnerability is an authentication bypass (CWE-287) in the OTP login mechanism where the plugin verifies the one-time code validity but fails to confirm that the authenticated account matches the user attempting to log in. An unauthenticated attacker with network access to the login interface can exploit this by providing any target user's phone number, completing the OTP challenge using their own phone, and gaining login access to that user's account. The flaw requires the OTP login feature to be explicitly enabled by the site administrator.
