The vulnerability stems from session-based reCaptcha bypass logic removed in the patches (785f4e2/0314e67). Both auth() and authCheck() checked $_SESSION['last_valid_captcha'] to skip captcha validation. The removal of these checks in the patch directly correlates with the described vulnerability where a single valid captcha response could bypass subsequent challenges. The file path and function names are explicitly shown in the commit diffs, confirming their involvement.
