No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Due to incomplete input validation in Idira Privileged Session Manager for SSH (PSMP) versions prior to 15.0.2, 14.6.3, 14.2.5, and 14.0.6, an authenticated, low-privileged user could potentially execute arbitrary commands on the PSMP host. CyberArk Security Bulletins: CA26-17 and CA26-18
