## What is CVE-2026-77084?

CVE-2026-77084 is a high-severity command injection vulnerability in N8n N8n, published on 20 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

n8n before 1.123.69 (and 2.x before 2.33.4 / 2.34.1) contains a code execution vulnerability in the Git node. The Git node executed certain repository-local git configuration values without neutralizing them, so any subsequent Git node operation against a repository containing a malicious value would execute it as the n8n process user. This is not reachable through the Git node's own configuration controls and requires a separate file-write vulnerability elsewhere to plant the malicious value.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

```text
Check this codebase for CVE-2026-77084 and fix it if it is affected.

What it is: CVE-2026-77084 is a high-severity command injection vulnerability in N8n N8n, published on 20 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-77084 in the wild and no public exploit code.

Affected product: N8n N8n. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
