- n8n
- CVE
- CVE-2026-86995
- Affected
- n8n before 1.123.76, 2.0.0 to 2.37.7, and 2.38.0 to 2.38.2
- Fixed in
- 1.123.76, 2.37.7, and 2.38.2
Last verified against sources: October 26, 2026
Am I affected?
n8n: affected n8n before 1.123.76, 2.0.0 to 2.37.7, and 2.38.0 to 2.38.2. Fixed in 1.123.76, 2.37.7, and 2.38.2.
- Check your version: run
npm ls n8n. Versions < 1.123.76 of n8n are affected. [1]
What to do now
- Upgrade to the fixed version: run
npm install n8n@1.123.76(first patched version 1.123.76). [1] - Upgrade to n8n 1.123.76, 2.37.7, or 2.38.2, or a later version. [1]
- If upgrading is not possible right away, restrict access to the n8n instance to fully trusted users only. [1]
- Disable the Git node by adding
n8n-nodes-base.gitto theNODES_EXCLUDEenvironment variable. [1] - Run the n8n process under a dedicated low-privilege OS user account to limit the scope of filesystem access. [1]
General practice, not from the source: if the affected software could read tokens or credentials, rotate them after upgrading; pin versions and review changes before updating tools your agents run.
What happened
- The Git node checked the repository that a fetch or pull targeted, but it wrote a
branch.<name>.remotevalue into the repository's own configuration without checking that value. [1] - A later fetch or pull took the remote from that configuration instead of from the checked parameter. [1]
- The patch checks the branch remote configuration the same way it checks the repository parameter. [1]
Impact
What was done
- The issue has been fixed in n8n versions 1.123.76, 2.37.7, and 2.38.2. [1]
