NivoCart through 2.5.1 contains a CAPTCHA bypass vulnerability that allows unauthenticated attackers to defeat form protection because the expected code is printed as plain text in the HTML. Attackers can fetch protected forms, extract the captcha_image value with a pattern match, and submit it to automate spam, registrations, reviews, and account deletion requests.
