n8n CVE-2026–21858 (“Ni8mare”)

This source details a critical security vulnerability known as CVE-2026–21858, or “Ni8mare,” which impacts the n8n automation platform. Because n8n often serves as a central hub connecting sensitive internal databases and cloud APIs, this flaw poses a severe risk to organisational infrastructure. An attacker can exploit improper request parsing to bypass security controls, eventually leading to unauthorised administrative access and remote code execution. The text warns that because these instances house high-value credentials, a breach can facilitate lateral movement throughout an entire network. To prevent a total system takeover, users are urged to patch immediately by upgrading to version 1.121.0 or later. Finally, the report recommends rotating all secrets and implementing network segmentation to protect against future exploitation.
