Description
The Podlove Podcast Publisher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Auphonic Webhook in all versions up to, and including, 4.5.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injection is triggered by submitting a request to the Auphonic webhook endpoint with any POST body where the status_string field is not the literal string 'Done', causing the full raw POST superglobal to be stored in the plugin log before any authentication key validation is performed.
