CVE-2026-108717
Combodo iTop 3.1.0 through 3.3.0 contains a missing authorization vulnerability in LinkSetController.php that allows authenticated console users to bypass profile grants by supplying arbitrary class and key parameters.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
