Name of the Vulnerable Software and Affected Versions PowerPress Podcasting plugin by Blubrry plugin for WordPress versions up to, and including, 11.9.18

Description The issue is related to Stored Cross-Site Scripting via the plugin's 'skipto' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 11.9.18, update to a version that addresses the insufficient input sanitization and output escaping issue in the 'skipto' shortcode. As a temporary workaround, consider restricting access to the 'skipto' shortcode for users with contributor-level access and above until a patch is available.
