CVE-2026-22686 (opens in a new tab)How to fix?
Upgrade enclave-vm to version 2.7.0 or higher.
Overview
enclave-vm is a Sandbox runtime for secure JavaScript code execution
Affected versions of this package are vulnerable to Protection Mechanism Failure via the exposure of a host-side Error object to sandboxed code, which retains its host realm prototype chain. An attacker can intentionally trigger a host error and traverse the prototype chain to access the host Function constructor, enabling execution of arbitrary JavaScript in the host context and access to sensitive resources such as environment variables, filesystem, and network.
