CVE-2026-25053 is a critical-severity OS Command Injection (CWE-78) vulnerability in N8N N8N. Its CVSS base score is 9.4 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 44th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
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.

CVE-2026-25053 is a critical vulnerability (CVSS 9.9, CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) classified under CWE-78 (OS Command Injection) affecting the Git node in n8n, an open-source workflow automation platform. Versions prior to 1.123.10 and 2.5.0 are vulnerable, where flaws in the Git node allow authenticated users with permissions to create or modify workflows to execute arbitrary system commands or read arbitrary files on the n8n host.
An attacker requires only low-privilege authenticated access (PR:L) and permission to create or modify workflows to exploit this remotely (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Exploitation changes the scope (S:C) and enables high-impact outcomes, including full host compromise through arbitrary command execution for potential remote code execution or data exfiltration via arbitrary file reads.
The n8n security advisory at https://github.com/n8n-io/n8n/security/advisories/GHSA-9g95-qf3f-ggrw states that the vulnerability has been patched in versions 1.123.10 and 2.5.0, recommending immediate upgrades for affected deployments.

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).
