Prior to version 3.11.4, Symbol.for override in setup-sandbox.js only intercepts 2 of 9 dangerous Node.js cross-realm symbols. Combined with the bridge's set/defineProperty/deleteProperty traps having no isDangerousCrossRealmSymbol key check, sandbox code can obtain real cross-realm symbols, write them to host objects, and control host-side behavior — verified with a full util.promisify hijack chain. This issue has been patched in version 3.11.4."},"products":[{"@id":"cpe:2.3:a:patriksimek:vm2:\\<_3.11.4:*:*:*:*:*:*:*","identifiers":{"cpe23":"cpe:2.3:a:patriksimek:vm2:\\<_3.11.4:*:*:*:*:*:*:*"}}],"status":"affected","action_statement":"No fixed version is published yet; monitor the upstream advisory.","timestamp":"2026-06-13T03:55:55.641Z"}]}
