CVE-2025-31966

HCL Sametime is vulnerable to broken server-side validation.

LOW 2.7EPSS 0.19%

Does this matter?

Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.

Description

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.
