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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
| Vendor | Product | Default status | Versions | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| n8n-io | n8n | unaffected |
