CVE-2026-92952

A flaw was found in vm2. The vm2 sandbox incompletely filters Node.js internal symbols, specifically nodejs.stream.disturbed and nodejs.stream.errored, across the sandbox boundary. This allows code running within the sandbox to obtain real host symbols and use them to corrupt the host-visible...

CVE-2026-92933

A flaw was found in vm2. The NodeVM component exposes the host util module, including the util.getCallSites function, to the sandbox as an unfiltered copy. On Node.js versions 22.9 and later, this allows sandboxed code to access util.getCallSites, which can return the host process's full call...

CVE-2026-92936

A flaw was found in vm2. Attacker-supplied code running within a sandbox can force the host-realm source transformer to throw a SyntaxError, for example, by providing malformed source to eval. By reading the error's stack property, the attacker can bypass sandbox-side host-path redaction. This...
