CVE-2026-5516
IBM WebSphere Application Server - Liberty 22.0.0.11 through 26.0.0.5 IBM WebSphere Application Server Liberty could allow a remote attacker to bypass security under limited conditions by exploiting a specific timing window.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
