CVE-2025-31966

Estado: AnalizadaBaja (2.7)—

HCL Sametime is vulnerable to broken server-side validation. While the application performs client-side input checks, these are not enforced by the web server. An attacker can bypass these restrictions by sending manipulated HTTP requests directly to the server.

CVSS
