CVE-2025-70336
📋 TL;DR
A stored cross-site scripting (XSS) vulnerability in PodcastGenerator 3.2.9 allows attackers to inject malicious scripts or HTML into podcast live item fields. When users view the affected pages, the injected code executes in their browsers, potentially compromising their accounts or sessions. This affects all PodcastGenerator 3.2.9 installations with the vulnerable 'Create New Live Item' feature enabled.

⚠️ Risk & Real-World Impact
Worst Case
Attackers steal administrator session cookies, gain full control of the PodcastGenerator instance, deface the site, or redirect users to malicious sites.
Likely Case
Attackers hijack user sessions, steal credentials, or perform actions on behalf of authenticated users.
If Mitigated
Limited impact with proper input validation and output encoding, though some script execution may still occur.
🎯 Exploit Status
Exploitation requires ability to create or edit live items. Public proof-of-concept exists in the referenced GitHub disclosure.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Monitor the official PodcastGenerator repository for updates. Consider applying input validation and output encoding fixes manually.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation and sanitization for TITLE, SHORT DESCRIPTION, and LONG DESCRIPTION fields to strip or encode HTML/script tags.
Content Security Policy (CSP)
allImplement a strict Content Security Policy header to prevent execution of inline scripts and unauthorized external resources.
🧯 If You Can't Patch
- Disable the 'Create New Live Item' feature if not required.
- Implement web application firewall (WAF) rules to block XSS payloads in the affected parameters.
🔍 How to Verify
Check if Vulnerable:
Test by creating a live item with a simple XSS payload like <script>alert('XSS')</script> in TITLE, SHORT DESCRIPTION, or LONG DESCRIPTION fields, then check if it executes on 'View All Live Items' or 'Live Stream' pages.Check Version:
Check the PodcastGenerator version in the admin panel or by examining the source code/configuration files.Verify Fix Applied:
After applying fixes, repeat the test with the same payload and verify no script execution occurs. Check that input is properly sanitized and output is encoded.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to live item creation endpoints with script-like content in parameters
- Multiple failed validation attempts on input fields
Network Indicators:
- HTTP requests containing script tags or JavaScript in TITLE, SHORT DESCRIPTION, or LONG DESCRIPTION parameters
SIEM Query:
source="web_server" AND (uri_path="/admin/live_items.php" OR uri_path LIKE "%/live_items%") AND (http_method="POST" OR http_method="PUT") AND (param_value LIKE "%<script>%" OR param_value LIKE "%javascript:%")
