Last modified
CVE-2026-85165 is a critical-severity vulnerability rated 9.9/10 on the CVSS scale. n8n versions before 2.36.2 contain an expression sandbox bypass vulnerability where free identifiers in spread, computed-key, switch-case, or class-extension positions resolve against process globals. Authenticated users with workflow-edit permission can mutate host objects through expression evaluation, with changes persisting process-wide until restart.. EPSS estimates a 0.57% chance of exploitation in the next 30 days.
