WS Form LITE <= 1.9.117 - CAPTCHA Bypass

Client-Side Enforcement of Server-Side Security
CVSS 5.3 (Medium)
Publicly Published May 23, 2023
Last Updated May 24, 2023


The WS Form LITE plugin for WordPress is vulnerable to CAPTCHA bypass in versions up to, and including, 1.9.117. This is due to the existence of a mechanism that allows the CAPTCHA to be bypassed if the client-side field is hidden (or omitted from the request). This makes it possible for unauthenticated attackers to bypass an intended protection mechanism for contact form submissions.
