How the CVE Works:
CVE-2025-1505 is a critical vulnerability in the Advanced AJAX Product Filters plugin for WordPress, affecting versions up to and including 1.6.8.1. The flaw arises due to insufficient input sanitization and output escaping of the ‘nonce’ parameter. This allows unauthenticated attackers to inject arbitrary web scripts into pages. When a user clicks on a malicious link, the injected script executes in their browser, potentially leading to session hijacking, data theft, or unauthorized actions on behalf of the user. The vulnerability is classified as Reflected Cross-Site Scripting (XSS) and is exploitable without authentication, making it highly dangerous.

What Undercode Say:
Exploitation:
- Attackers craft a malicious URL with a script payload in the ‘nonce’ parameter.
- Example payload:
https://example.com/?nonce=<script>alert('XSS')</script>. - Victims clicking the link execute the script in their browser.
