CVE-2026-86081
n8n is an open source workflow automation platform.
Overview
CVE-2026-86081 is a known-severity vulnerability. It was published on September 8, 2026.
Technical description
n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the Git node clone operation matched an attacker-controlled destination path against the default N8N_BLOCK_FILE_PATTERNS regular expression. The pattern ^(./).git(/.)$ allowed catastrophic backtracking and ran synchronously in the main n8n process. An authenticated workflow editor could therefore freeze the instance with one workflow execution; the affected default is declared in packages/@n8n/config/src/configs/security.config.ts. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.
