The Podlove Podcast Publisher plugin for WordPress, up to and including version 4.2.2, is vulnerable to Cross-Site Request Forgery (CSRF) due to missing or incorrect nonce validation in the `ajax_transcript_delete()` function. This vulnerability allows unauthenticated attackers to delete arbitrary episode transcripts by tricking a site administrator into performing an action, such as clicking on a malicious link. The lack of proper nonce validation means that the plugin fails to verify the authenticity of the request, enabling attackers to forge requests and execute unauthorized actions on behalf of the administrator.
DailyCVE Form:
Platform: WordPress
Version: <= 4.2.2
Vulnerability: CSRF
Severity: Critical
Date: 03/06/2025
What Undercode Say:
Exploitation:
- Attackers craft a malicious link or form that triggers the `ajax_transcript_delete()` function.
- The link is sent to a site administrator, often disguised as a legitimate request.
- When the administrator clicks the link, the forged request is sent to the server, deleting the transcript without proper validation.
Protection:
- Update the Podlove Podcast Publisher plugin to the latest version if a patch is available.
- Implement proper nonce validation in the `ajax_transcript_delete()` function to ensure requests are authenticated.
- Use WordPress hooks to validate user permissions before executing sensitive actions.
Code Example for Nonce Validation:
function ajax_transcript_delete() {
if (!isset($_POST[bash]) || !wp_verify_nonce($_POST[bash], 'delete_transcript_nonce')) {
wp_die('Security check failed');
}
// Proceed with deletion logic
}
Analytics:
- Attack Vector: Network (requires user interaction)
- Impact: Unauthorized data deletion
- CVSS Score: 8.8 (High)
Commands:
1. Check Plugin Version:
wp plugin get podlove-podcast-publisher --field=version
2. Deactivate Plugin:
wp plugin deactivate podlove-podcast-publisher
Mitigation Steps:
- Educate administrators about the risks of clicking untrusted links.
- Implement Content Security Policy (CSP) headers to reduce the risk of CSRF attacks.
- Regularly audit plugin code for missing nonce validation.
