CVE-2026-50040
Storage Concentrator (SC & SCVM) is vulnerable to reflected cross-site scripting due to unsanitized content being echoed back in 404 error pages. An attacker can craft a malicious URL that, when visited by an authenticated user, causes arbitrary script content to execute within the victim's browser session in the context of the application. This could be leveraged to steal session cookies, redirect users, or perform unauthorized actions on behalf of the victim.
