CyberRota Analysis
AI-GeneratedThe n8n workflow automation platform is vulnerable to a denial-of-service condition due to a flaw in the Git node clone operation, which allows an authenticated user to exploit the default regular expression for destination paths. This vulnerability can lead to catastrophic backtracking, potentially freezing the n8n instance during workflow execution. Organizations using affected versions should prioritize upgrading to versions 1.123.76, 2.37.7, or 2.38.2 to mitigate this risk.

Original NVD 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.
