Description

The Jetpack Scan team identified a Reflected Cross-Site Scripting in the Login Form of the Patreon WordPress plugin before 1.7.2. The WordPress login form (wp-login.php) is hooked by the plugin and offers to allow users to authenticate on the site using their Patreon account. Unfortunately, some of the error logging logic behind the scene allowed user-controlled input to be reflected on the login page, unsanitized.

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 Patreon WordPress — From 1.7.2 (including) to 1.7.2 (excluding)
  • patreon patreon_wordpress — Before 1.7.2
