CVE-2026-92961 vm2 before 3.11.6 Memory Exhaustion DoS via bufferAllocLimit Bypass

vm2 before 3.11.6 fails to enforce bufferAllocLimit on ArrayBuffer, SharedArrayBuffer, and TypedArray constructors, allowing attackers to allocate arbitrary host memory. Attackers can bypass the buffer allocation cap by using these V8 intrinsics to exhaust host process memory and trigger...

CVE-2026-92960 vm2 before 3.11.6 Process-wide State Exposure via os and dns

vm2 before 3.11.6 fails to restrict access to os and dns builtins under the builtin: '' configuration, allowing sandbox code to read host process identity and network topology. Attackers can invoke dns.setServers to hijack the host process DNS resolver globally, redirecting all subsequent host DN...

CVE-2026-92960

vm2 (a Node.js sandboxing library) versions before 3.11.6 fail to restrict access to the os and dns builtins when configured with builtin: ['*']. This allows sandboxed code to read the host process identity and network topology . Critically, an attacker can invoke dns.setServers() to hijack the h...

CVE-2026-92959 vm2 before 3.11.8 allowAsync Bypass via Promise Thenable

vm2 before 3.11.8 does not fully enforce the allowAsync: false option in VM and NodeVM. While localPromise.prototype.then is replaced with a handler that throws 'Async not available', the sandbox's Promise static methods Promise.resolve, Promise.all, Promise.race, Promise.any, and...

CVE-2026-92959

CVE-2026-92959 affects vm2 (a Node.js sandboxing library) versions prior to 3.11.8 . The vulnerability lies in the incomplete enforcement of the allowAsync: false option in VM and NodeVM. Although localPromise.prototype.then is patched to throw 'Async not available', the sandbox's Promise static ...

CVE-2026-92958 vm2 before 3.11.7 Denylist Bypass via fs/promises

vm2 through 3.11.6 contains a builtin-module denylist bypass in NodeVM. When the embedder uses the builtin wildcard together with negative entries e.g. require: builtin: '', '-fs', '-childprocess' , negative entries are matched by exact module name in lib/builtin.js, so -fs removes only the built...

CVE-2026-92958

vm2 (a Node.js sandboxing library) versions through 3.11.6 contain a builtin-module denylist bypass in NodeVM . When embedders use the wildcard with negative entries (e.g., -fs), matching is done by exact module name in lib/builtin.js, so fs/promises is not blocked. Sandboxed code can therefore c...
