Critical n8n Flaw Expose Automation Nodes to Full RCE

Three critical vulnerabilities were published for the n8n workflow automation platform that allow authenticated users with low privileges to achieve remote code execution, read arbitrary files, or bypass a prior patch via prototype pollution and argument injection. Affected versions are older than 1.123.43, 2.20.7, and 2.22.1; n8n released fixes and recommends immediate upgrades or mitigations (restricting workflow permissions and disabling affected nodes) due to the high-impact, network-exploitable nature of the flaws.
