Updated under an hour ago ()

Does this affect you?

It affects Perforce P4 (Helix Core). Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

Perforce P4 Search prior to 2026.4.2 trusts a client-supplied address when validating certain authentication requests. An attacker holding a stolen P4 Server ticket can bypass host-based ticket restrictions and trusted-address controls, gaining access to P4 Search as the ticket's owner.
