Executive ViewAI

Why It Matters

Organizations using n8n-workflows Main Commit ee25413 face critical risk from CVE-2025-55526, a path traversal vulnerability rated CVSS 9.1. This could allow attackers to access or modify files outside intended directories, potentially exposing sensitive configuration or credentials. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.

Business Impact: Severe
Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Restrict file upload functionality via WAF; (2) Implement allowlist-based file type validation; (3) Use chroot/containerization to limit filesystem access.
