CVE-2022-3831Public exploitNetwork attack vector

Administrator stored XSS via unescaped settings fields

Published Nov 28, 2022 · Updated Apr 25, 2025

Stored XSS in Robert Peake Login No Captcha reCAPTCHA 1.6 and earlier allows remote authenticated users to execute script through crafted settings. The plugin settings page saves unsanitized input and returns it unescaped inside input elements, so an injected event-handler attribute runs after reload. Administrator privileges are required, and a user must refresh the settings page and interact with the affected field; script execution occurs in that viewer's browser.
