Description
The Paid Membership Subscriptions plugin for WordPress is vulnerable to a reCAPTCHA bypass in all versions up to, and including, 3.1.3. The reCAPTCHA v3 validation accepted an empty token when the request included a 'pms_recaptcha_init_error' nonce that is printed on the public form, and the login form check could be altered or skipped by posting the bare 'pms_login' or 'wppb_login' flags to wp-login.php. This makes it possible for unauthenticated attackers to bypass the reCAPTCHA protection enabled by the site owner on registration and login forms, for example to perform automated sign-ups or brute-force login attempts.
