Stored XSS in Podlove Podcast Publisher WordPress Plugin via Auphonic Webhook

Publication date: 2026-10-10

Last updated on: 2026-10-10

Assigner: Wordfence

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.

Executive Summary

The Podlove Podcast Publisher WordPress plugin up to version 4.5.6 has a stored cross-site scripting (XSS) vulnerability. Unauthenticated attackers can inject malicious scripts via the Auphonic webhook by sending a POST request with a status_string field not equal to 'Done'. The raw POST data is stored in logs without proper sanitization, allowing scripts to execute when users view those logs.

Detection Guidance

Check WordPress plugin logs for suspicious POST requests to the Auphonic webhook endpoint where status_string is not 'Done'. Inspect logs for raw POST data storage or unexpected script injections. Use WordPress security plugins to monitor for unauthorized script execution in logs or pages.

Impact Analysis

Attackers could steal user sessions, deface your website, or redirect visitors to malicious sites. Since the payload executes when logs are viewed, any user with access to the WordPress admin panel could trigger the attack. The vulnerability requires no authentication, making it easier for remote attackers to exploit.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR's integrity and confidentiality principles. For HIPAA, it may expose protected health information if podcast content or user data is compromised. Organizations must patch quickly to maintain compliance.

Mitigation Strategies

Update the Podlove Podcast Publisher plugin to version 4.5.7 or later. Ensure webhook requests are authenticated by validating the 'podlove-auphonic-production' parameter and 'authkey' before processing. Review and sanitize existing logs for any injected scripts.
