The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-30804 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) that enables remote code execution through file uploads. It affects Pandora FMS versions from 777 through 800. The vulnerability has 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 on confidentiality, integrity, and availability.

A remote attacker with high privileges can exploit this vulnerability over the network with low attack complexity and no user interaction required. Successful exploitation allows the attacker to upload malicious files, leading to arbitrary remote code execution on the affected system.
