CVE-2026-71189

What is CVE-2026-71189?

A security flaw exists in the application framework that allows an attacker to craft a malicious request. If this request is processed by another user’s session, it can execute harmful JavaScript code within the user's browser. This typically happens when the application does not properly validate or sanitize user inputs, enabling an attacker to inject scripts that could steal sensitive information or hijack user sessions. It is crucial for administrators and users to apply necessary mitigations and monitor for suspicious activities that may exploit this vulnerability.
