Description

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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Unknown reCaptcha by WebDesignBy — Before 2.0
