Description
CVE-2026-55401 is a null dereference vulnerability in the load-balancing subsystem of Absolute Security's Secure Access servers prior to version 14.57. An unauthenticated attacker can send a specially crafted packet to a Secure Access server with load balancing enabled, causing the internal load balancer to crash. Despite the crash, the server continues to accept connections and can still issue failover to connected clients. The vulnerability has a medium severity score of 6.9 (CVSS 4.0).
