CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:HSummary
CVE-2026-26318 is a high-severity OS Command Injection (CWE-78) vulnerability in Systeminformation Systeminformation. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 36% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-26318 is a command injection vulnerability (CWE-78) in the systeminformation library, a System and OS information tool for Node.js. Versions prior to 5.31.0 are affected due to unsanitized output from the `locate` command within the `versions()` function, allowing arbitrary command execution.
The vulnerability requires local access (AV:L), low attack complexity (AC:L), and low privileges (PR:L), with no user interaction (UI:N). Exploitation leads to a scope change (S:C) and high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), resulting in a CVSS v3.1 base score of 8.8. A local low-privileged attacker can inject and execute commands, potentially achieving full system compromise.
Version 5.31.0 of systeminformation resolves the issue. Additional details are available in the GitHub security advisory at GHSA-5vv4-hvf7-2h46 and the fixing commit b67d3715eec881038ccbaace2f2711419ac3e107.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
