Altair PBS Professional through 19.1.2 allows Privilege Escalation because an attacker can send a message directly to pbs_mom, which fails to properly authenticate the message.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.97%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
