CVE-2026-25053 is a critical vulnerability in the n8n workflow automation platform affecting the Git node in versions prior to 1.123.10 and 2.5.0. The flaw allows authenticated users who have permission to create or modify workflows to abuse Git node functionality to execute arbitrary operating system commands on the host running n8n. Available reporting also indicates the same vulnerable behavior can be used to read arbitrary files from the host. The issue is characterized as an operating system command injection in privileged workflow functionality exposed through the Git node, creating a direct path from workflow-level access to host-level compromise.

Repository is a small PoC labeled CVE-2026-25053 consisting of 4 files: (1) README.md with only the CVE title, (2) .gitattributes setting '* filter=evil' to apply a Git filter to all files, (3) file.txt containing a Git config snippet defining filter "evil" with clean/smudge commands set to "calc.exe" (Windows command execution demo), and (4) workflow.json, an n8n workflow that automates exploitation steps. The n8n workflow structure: Manual Trigger → Git node (clone) clones https://github.com/yadhukrishnam/CVE-2026-25053 into C:\Users\yadhu\.n8n-files\poc → Read/Write node reads a local file (C:\Users\yadhu\.n8n-files\test\file.txt) → Read/Write node appends content into C:\Users\yadhu\.n8n-files\poc\.git\config (injecting the malicious filter definition) → Git node runs 'add' on file.txt. With the attribute forcing the filter and the filter commands defined, subsequent Git operations that invoke clean/smudge can execute the configured command (calc.exe). This is a command-execution PoC rather than a scanner/detector, and it is not a Metasploit/Nuclei module; it is an n8n automation workflow demonstrating a Git-filter-based execution chain.
