## Description

The PowerPress Podcasting plugin by Blubrry plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Value Time Split (VTS) remote item title in all versions up to, and including, 11.18.2, due to insufficient input sanitization and output escaping. The 'powerpress-jquery-vts-add-edit-recipient' action stores the submitted episode title without sanitizing it, and the episode box prints it without escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts into their own posts that will execute whenever a user, such as an administrator reviewing the post, opens the post editing screen.
