@nyariv/sandboxjs has a Sandbox Escape vulnerability

Summary As Map is in SAFEPROTOYPES, it's prototype can be obtained via Map.prototype. By overwriting Map.prototype.has the sandbox can be escaped. Details This is effectively equivalent to CVE-2026-25142, but without lookupGetter let was used during testing, it turns out the let implementation is...
