Description
The SMS Alert WordPress plugin before version 3.9.8 contains an authentication flaw where the "mobile verified" session flag is not properly bound to the verified phone number. This allows an unauthenticated attacker who verifies an OTP on their own phone to supply a different phone number during login, enabling them to log in as any user, including administrators with a billing phone on file. The vulnerability has a high severity score of 7.5 and impacts confidentiality but not integrity or availability.
