Description

The Nested Pages WordPress plugin before 3.2.15 does not properly escape post titles before outputting them into HTML attributes on an administrative listing screen, allowing users with the Editor role (or Contributor/Author when the Nested Pages WordPress plugin before 3.2.15 is enabled for the post type) to inject arbitrary JavaScript that executes in the session of any higher-privileged user who views that screen.

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.
