Critical 9.9
In plain English
A critical-severity security flaw in n8n. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 20.4% (higher than 98% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
n8n contains a critical Remote Code Execution (RCE) vulnerability in its workflow Expression evaluation system. Expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime. An authenticated attacker could abuse this behavior to execute arbitrary code with the privileges of the n8n process. Successful exploitation may lead to full compromise of the affected instance, including unauthorized access to sensitive data, modification of workflows, and execution of system-level operations.
