Vulnerability Title
Podlove Podcast Publisher <= 4.5.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'episode_contributor[..][..][comment]' Parameter
Source: CVE Program / CVE List V5
Vulnerability 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.
