Vulnerability from github – Published: 2026-04-23 09:32 – Updated: 2026-04-23 15:38

Details

The reCaptcha by WebDesignBy WordPress plugin before 2.0 does not sanitize or escape the Site Key setting before outputting it in a JavaScript string context via the grecaptcha_js() function. This allows administrators on multisite installations (who do not have the unfiltered_html capability) to inject arbitrary JavaScript that executes for all visitors to the WordPress login page.

Severity ?

3.5 (Low)
