CVE-2026-47210

A flaw was found in vm2, an open-source virtual machine VM sandbox for Node.js. This sandbox escape vulnerability allows an attacker to execute arbitrary code in the host process. This occurs when untrusted code is executed with asynchronous async support on runtimes that expose WebAssembly...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. This flaw occurs when dropping packets during a bulk transfer from a SPICE client, due to the packet queue being full. A malicious SPICE client could exploit this flaw to call the free function in...

Astra Linux – Vulnerability in Qemu

A use-after-free vulnerability was discovered in the virtio-net device of QEMU. This vulnerability can occur when the address of the descriptor belongs to the non-direct access region, due to the numbuffers being set after the virtqueue elem has been unmapped. A malicious guest can exploit this...

CVE-2026-47210

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, a sandbox escape vulnerability in vm2 allows arbitrary code execution in the host process when untrusted code is executed with async support on runtimes exposing WebAssembly JSPI WebAssembly.promising / WebAssembly.Suspending...

CVE-2026-47208

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, VM2 suffers from a sandbox breakout vulnerability. This allows attackers to write code which can escape from the VM2 sandbox and execute arbitrary commands on the host system. This issue has been patched in version 3.11.4...

CVE-2026-47140

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM blocks several dangerous Node.js builtins such as module, workerthreads, cluster, vm, repl, and inspector. However, the denylist misses process and inspector/promises. Both can be used from sandboxed code to reach...

CVE-2026-47210

Summary : CVE-2026-47210 affects the vm2 sandbox prior to version 3.11.4, where a JSPI-backed Promise pathway can bypass Promise species hardening via WebAssembly.promising/WebAssembly.Suspending, potentially exposing a host-originated rejection object to attacker-controlled logic and breaking sa...
