Summary
The Podlove Podcast Publisher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Auphonic Webhook in versions up to and including 4.5.6. Insufficient input sanitization and output escaping allow unauthenticated attackers to inject arbitrary web scripts. The injection is triggered by submitting a request to the webhook endpoint with a status_string other than 'Done'.
Risk Assessment
The risk includes script execution in users' browsers, potentially leading to data theft or session hijacking. The attack is possible without authentication, and data is stored before key validation.
Recommendation
Update the Podlove Podcast Publisher plugin to the latest version. Also secure the webhook endpoint to validate the key before storing data.

Original NVD description (English source)
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.
