Description

The PowerPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in versions up to, and including, 10.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. NOTE: A partial fix for the issue was introduced in version 10.0.1, and an additional patch (version 10.0.2) was released to address a workaround.

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

  • blubrry PowerPress Podcasting plugin by Blubrry — Up to and including 10.0
  • blubrry powerpress — Up to and including 10.0
