Bottom Line: n8n contains multiple vulnerabilities that enable code execution and data manipulation and must be patched immediately.
Multiple vulnerabilities have been discovered in n8n that allow attackers to bypass security mechanisms and execute arbitrary code. The automation tool is widespread in many enterprise environments.
Following the CERT-Bund warning WID-SEC-2026-2489, multiple security vulnerabilities exist in the workflow automation platform n8n. An attacker can exploit these to bypass security measures and thereby perform unauthorized actions.
The vulnerabilities enable a range of critical attack scenarios: denial-of-service attacks, disclosure of information, manipulation of files, SQL injection attacks, and the execution of arbitrary code. The diversity of possible attack types points to fundamental validation and authorization issues.
As a CISO, updating n8n instances should be carried out with high priority. Affected deployments should be inventoried immediately and checked for available patches. Until the update is applied, access restrictions and network segmentation should be implemented to minimize exposure risk.
