Description
pH7Builder (pH7 Social Dating CMS) before 19.3.0 contains a CAPTCHA bypass vulnerability that allows unauthenticated attackers to skip form validation by supplying a client-chosen form ID to PFBC Form::isValid(). Attackers can load a CAPTCHA-free form like login or search, then submit its ID with contact, comment, forum, invite or signup data to automate abuse.
