WordPress Plugin Vulnerabilities
SMS Alert 4.0.0 - Unauthenticated Authentication Bypass via Login with OTP
Description
The plugin does not verify that the account being logged in is the one the verified one-time code belongs to, allowing unauthenticated attackers to sign in as any user with a stored phone number, including an administrator, by completing a code challenge on a phone they control.
Exploitation requires the plugin's OTP login feature to be enabled, which is not the default.
