CVE-2026-5325: XSS in Simple Customer Relationship Management System

The XSS vulnerability in Simple Customer Relationship Management System allows an attacker to inject arbitrary JavaScript code into the application. This code can then be executed in the context of a user's browser when they visit a page containing the injected script. An attacker could leverage this to steal session cookies, redirect users to malicious websites, or modify the content of the application. The impact is amplified if the application is used to store sensitive customer data, as an attacker could potentially access or modify this information. The publicly disclosed nature of this vulnerability increases the likelihood of exploitation.

The primary mitigation for CVE-2026-5325 is to upgrade to a patched version of Simple Customer Relationship Management System. Since a fixed version is not specified, consider reverting to a previous known-good version if upgrading causes instability. As a temporary workaround, implement strict input validation and output encoding on the Description field in /create-ticket.php to sanitize user-supplied data. Consider using a Web Application Firewall (WAF) with XSS filtering rules to block malicious requests. Verify the fix by attempting to inject a simple JavaScript payload (e.g., <script>alert('XSS')</script>) through the Description field after applying the mitigation.
