CVE-2026-9862Network attack vector

Unauthenticated command execution via autoregistration input

Published Jun 15, 2026 · Updated Jun 15, 2026

OS command injection in Fortra Core Privileged Access Manager (BoKS) allows remote attackers to execute commands during autoregistration. In affected boks-server 8.1.0.0 through 8.1.0.22 and 9.0.0.0 through 9.0.0.4, boks_autoregisterd fails to neutralize command elements in network-supplied input; Fortra has not identified the input field or command-building path. Network access to TCP port 6507 is sufficient, and successful exploitation runs commands with the privileges of the service.
