CVE-2026-56352· NVD / CVE Program· CNA VulnCheck

n8n - Arbitrary File Read and Execution via ExecuteWorkflow localFile Parameter

Noroxi assessment

Priority: Monitor (action score 21/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.32% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: n8n n8n 2.19.3.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to n8n n8n 2.19.3 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

n8n before 2.19.3 contains a file path restriction bypass in the legacy ExecuteWorkflow node's localFile source option, which reads workflow files from disk without the file-access checks enforced by other file-reading nodes. Although hidden from the UI since v1.2, it remains reachable via the REST API. An authenticated user with permission to create or modify workflows can supply an arbitrary file path to bypass the N8N_RESTRICT_FILE_ACCESS_TO restriction and determine whether arbitrary files exist on the host; where the targeted path contains a valid workflow JSON file, that file can additionally be loaded and executed.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
