CVE-2026-92947 vm2 before 3.11.7 Memory Disclosure via Buffer Pool

vm2 before 3.11.7 exposes Node's shared Buffer pool to sandboxed code, allowing disclosure of host memory used by Buffer.from, Buffer.concat, and related allocations. Sandboxed code can read and write to host-realm buffers by acquiring ArrayBuffers from small allocations, leading to sensitive dat...

vm2 before 3.11.7 exposes Node's shared Buffer pool to sandboxed code, allowing disclosure of host memory used by Buffer.from, Buffer.concat, and related allocations. Sandboxed code can read and write to host-realm buffers by acquiring ArrayBuffers from small allocations, leading to sensitive dat...

CVE-2026-92948

vm2 (a Node.js sandboxing library) versions 3.9.6 through 3.11.6 are vulnerable to a sandbox escape on Node.js 24+ when the embedder explicitly allows the node:test builtin. On Node.js 24, module.builtinModules exposes the scheme-only key node:test, which bypasses vm2's DANGEROUS_BUILTINS family-...

CVE-2026-92948 vm2 3.9.6 through 3.11.5 Sandbox Escape via node:test

vm2 versions = 3.9.6 and therefore executes arbitrary JavaScript in an unrestricted host Node process outside the NodeVM sandbox. Fixed in vm2 3.11.7...

CVE-2026-92947

CVE-2026-92947 affects the vm2 Node.js sandboxing library prior to version 3.11.7 . The vulnerability arises because Node's shared Buffer pool is exposed to sandboxed code: sandboxed scripts can acquire ArrayBuffers from small allocations (e.g., Buffer.from, Buffer.concat), gaining read and write...

CVE-2026-92948 vm2 3.9.6 through 3.11.5 Sandbox Escape via node:test

CVE-2026-92946

vm2 before 3.11.7 contains a remote code execution vulnerability triggered when require.external is enabled without an explicit require.root that excludes node_modules. Under these conditions, sandboxed code can require vm2's own package, instantiate an unrestricted NodeVM instance , and execute ...

CVE-2026-92946 vm2 before 3.11.7 Remote Code Execution via require.external

vm2 before 3.11.7 contains a remote code execution vulnerability when require.external is enabled without an explicit require.root that excludes nodemodules. Sandboxed code can require vm2's own package, instantiate an unrestricted NodeVM instance, and execute arbitrary host OS commands via...

CVE-2026-92945 vm2 before 3.11.7 Module Allowlist Bypass via Prefix Matching

vm2 before 3.11.7 contains a module allowlist bypass vulnerability in isPathAllowedForModule that uses raw string prefix matching instead of boundary-anchored comparison. Attackers can reach non-allowlisted packages sharing a prefix with allowlisted modules by performing relative requires from...

CVE-2026-92945

vm2 before 3.11.7 contains a module allowlist bypass in the isPathAllowedForModule function. The root cause is the use of raw string prefix matching instead of a boundary-anchored comparison, allowing attackers to reach non-allowlisted packages that share a name prefix with an allowlisted module....

CVE-2026-92944 vm2 3.10.2 through 3.11.6 Sandbox Escape via Promise Protector

vm2 versions 3.10.2 through 3.11.6 contain a sandbox escape vulnerability on Node.js 26 where Promise.prototype.finally bypasses vm2's wrapper protections due to a stale PromiseThenLookupChain protector in V8 14.6. Attackers can exploit this by creating an async function that returns a Promise wi...
