How to Fix CVE-2025-57749

To remediate this vulnerability, upgrade all affected N8n dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

n8n fixed: 1.106.0 
npm install n8n@1.106.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls n8n

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-57749, inspect your project dependencies using npm:

npm ls n8n

Analyze the terminal output to locate any version of N8n in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.106.0), your application is affected.

Note: The npm ls n8n command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-59: Improper Link Resolution Before File Access ('Link Following'), where the product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. In N8n, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact A symlink traversal vulnerability was discovered in the `Read/Write File` node in n8n. While the node attempts to restrict access to sensitive directories and files, it does not properly account for symbolic links (symlinks). An attacker with the ability to create symlinks—such as by using the `Execute Command` node—could exploit this to bypass the intended directory restrictions and read from or write to otherwise inaccessible paths. Users of _n8n.cloud_ are not impacted. ### Patches Affected users should update to version 1.106.0 or later. ### Workarounds Until the patch is applied: - Disable or restrict access to the `Execute Command` node and any other nodes that allow arbitrary file system access. - Avoid using the `Read/Write File` node on untrusted paths or inputs that could be manipulated via symlinks.
