CVE-2026-67554
An authenticated attacker can craft a disposition frame with large or illegal ranges causing excessive CPU usage due to naive range handling, leading to denial of service.
Does this matter?
Lower severity and a low EPSS score (0.65%). Track it; it rarely justifies an emergency change on its own.
