Change History

CVE-2026-55401 is a null dereference vulnerability on the load-balancing
 sub-system of Secure Access servers prior to 14.57. Attackers can send 
an unauthenticated packet to a Secure Access server with load balancing 
enabled, which results in the internal load balancer crashing. After a 
successful attack, the Secure Access server is still able to accept 
connections and is still able to issue a failover to connected clients. ‍ https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L
