The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical remote code execution vulnerability in n8n workflow automation platform to its Known Exploited Vulnerabilities catalog. CVE-2025-68613, an expression injection flaw, allows attackers to execute arbitrary code on affected systems running the popular automation tool.

The vulnerability carries a severe CVSS score of 9.9 and affects thousands of exposed instances. Security researchers have identified approximately 24,700 n8n instances that remain publicly accessible and potentially vulnerable to exploitation. CISA's addition to the KEV catalog confirms that threat actors are actively exploiting this flaw in the wild.

The security shortcoming stems from improper input validation in n8n's expression handling mechanism, allowing attackers to inject malicious code through crafted workflow expressions. When processed, these malicious expressions can lead to complete system compromise, enabling attackers to execute commands with the same privileges as the n8n service.

A patch for CVE-2025-68613 has been released by the n8n development team, though the specific version numbers and deployment timeline were not detailed in available reports. Organizations running n8n instances should immediately apply available security updates and review their exposure to prevent potential compromise.
