CVE-2026-45172: CWE-78: Improper Neutralization of Special Elements used in an OS Command in CyberArk Software, a Palo Alto Networks Company PAM Self-Hosted, Privilege Cloud
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
AI Analysis
Technical Summary
This vulnerability (CVE-2026-45172) arises from incomplete input validation in CyberArk's Idira PSMP for SSH, versions before 15.0.2, 14.6.3, 14.2.5, and 14.0.6. It enables an authenticated user with low privileges to execute arbitrary OS commands on the PSMP host due to improper neutralization of special elements used in OS commands (CWE-78). The CVSS 4.0 base score is 8.7, indicating high severity with network attack vector, low attack complexity, no user interaction, and partial confidentiality, integrity, and availability impacts. No vendor advisory or patch links are provided, and remediation level is not specified.
Potential Impact
An authenticated low-privileged user could exploit this vulnerability to execute arbitrary commands on the PSMP host, potentially leading to unauthorized system control or compromise. The impact affects confidentiality, integrity, and availability with high scope impact as indicated by the CVSS vector. This could allow attackers to escalate privileges or disrupt system operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the CyberArk Security Bulletins CA26-17 and CA26-18 for current remediation guidance. Until an official fix is available, restrict access to the affected PSMP versions to trusted users only and monitor for suspicious activity related to command execution. Follow vendor advisories closely for updates.
