CVE-2026-34188
Published: 13 April 2026
Summary
CVE-2026-34188 is a high-severity OS Command Injection (CWE-78) vulnerability in Artica Pandora Fms. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 31.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-34188 is an improper neutralization of special elements used in an OS command vulnerability that enables OS command injection via Event Response execution. This flaw affects Pandora FMS versions from 777 through 800. It is classified under CWE-78 and carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.
An attacker with high privileges (PR:H) can exploit this vulnerability over the network (AV:N) with low complexity (AC:L) and without requiring user interaction (UI:N). Successful exploitation allows arbitrary OS command injection, resulting in high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), potentially enabling full system compromise on the affected Pandora FMS instance.
Pandora FMS has documented this vulnerability in its security advisories, available at https://pandorafms.com/en/security/common-vulnerabilities-and-exposures/. Security practitioners should consult this resource for details on patches and mitigation steps.
