Kerentanan Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') pada n8n. Skor CVSS 3.1 8.8 (High) menurut NVD.

Deskripsi (NVD)

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.
