CVE-2026-103254
NVD: n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain a path traversal vulnerability in signed resume URL generation for Send-and-Wait approvals. NVD: Attackers with workflow creation permissions can mint valid approval URLs for gates in projects they cannot access by exploiting unresolved traversal sequences in caller-controlled node IDs, enabling cross-project approval forgery. OSV: n8n before 1.123.80, 2.39.6, and 2.40.1 Path Traversal via Resume URL Generation
