CVE-2026-75966 Details
Description
The Podlove Podcast Publisher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'episode_contributor[..][..][comment]' Parameter in all versions up to, and including, 4.5.5 due to insufficient input sanitization and output escaping. This makes it possible for 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. The contributor comment is stored in a plugin-managed custom table, bypassing WordPress core's wp_kses_post filter, and the save_post hook fires without a nonce check, meaning any user who can edit posts can exploit this without further preconditions.
A stored cross-site scripting vulnerability has been identified in the Podlove Podcast Publisher plugin for WordPress, affecting all versions up to and including 4.5.5. The issue arises from inadequate input sanitization and output escaping in the 'episode_contributor[..][..][comment]' parameter. This vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages, which are executed when users access the affected page. The injected comments are saved in a custom table managed by the plugin, bypassing WordPress's standard sanitization filters. Additionally, the mechanism for saving these comments lacks proper nonce verification, enabling exploitation by any user who can edit posts.
