## What is CVE-2026-79898?

Fortra BoKS Manager contains a command injection vulnerability in crlserver. An authenticated user authorized to add CRL URLs through BCC, the WSI REST or SOAP API, or the cacrl command-line interface could cause shell command substitution to be processed by crlserver as root on the BoKS Master. BCC and WSI provide network-accessible administration paths and do not require a local sudo or suexec rule; non-root use of cacrl requires such a rule.
