CVE-2026-92961 (opens in a new tab)How to fix?
Upgrade org.webjars.npm:vm2 to version 3.11.6 or higher.
Overview
org.webjars.npm:vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via sandbox escape through cross-realm Node.js internal symbol injection. In lib/bridge.js and lib/setup-sandbox.js, the isDangerousCrossRealmSymbol check and the Symbol.for override previously covered only a subset of dangerous nodejs.* symbols (util.inspect.custom, rejection, and util.promisify.custom), leaving seven additional Node-internal symbols accessible to sandbox code. An attacker can install these symbols on host-realm objects exposed to the sandbox, hijacking host-side control flow through Node's duck-typing checks and internal hooks (e.g., via util.promisify hijack or stream brand spoofing), ultimately causing a denial of service or potentially achieving sandbox escape.
