CLEANSTART-2026-ZC70101 — vm2 before 3

Affected: CleanStart: n8n

Security vulnerability affects the n8n package. vm2 before 3.

fkie_cve-2026-92934

vm2 before 3.11.8 contains an incomplete fix for Error.cause sanitization that allows sandbox escape when revisited host-wrapped AggregateError objects are caught within a single exception handler traversal. Attackers can exploit cycle detection bypass in handleException to access unsanitized host proxies embedded in the errors array, enabling full remote code execution and process information disclosure from the sandbox.
