CVE-2026-92956 vm2 3.10.1 through 3.11.6 Sandbox Escape via WebAssembly.compileStreaming

vm2 versions 3.10.1 through 3.11.6 contain a sandbox escape reachable from a default new VM sandbox when running on Node.js 26. WebAssembly.compileStreaming and WebAssembly.instantiateStreaming can produce a raw host-realm Promise that rejects with a host-realm error object; by controlling...

CVE-2026-92954 vm2 3.10.0 through 3.11.7 Denial of Service via Host Promise

vm2 is a sandbox library for running untrusted JavaScript in Node.js. In versions = 3.10.0 and = 3.11.7, Promises returned from the host realm into the sandbox are not marked as handled at the bridge boundary; only Promises created inside the sandbox are wrapped with a rejection-swallowing handle...

CVE-2026-92951

vm2 prior to version 3.11.7 is affected by an incorrect authorization flaw in its external package allowlist mechanism. The root cause is the use of non-exact substring matching instead of full package-name boundary validation, allowing an attacker to require a colliding package name that merely ...

CVE-2026-92951 vm2 before 3.11.7 Module Allowlist Bypass via Custom Resolver

vm2 before 3.11.7 contains an incorrect authorization vulnerability in the external package allowlist check that uses non-exact substring matching instead of full package-name boundary validation. Attackers can bypass the allowlist by requiring a colliding package name that contains an allowliste...

CVE-2026-92951 vm2 before 3.11.7 Module Allowlist Bypass via Custom Resolver

vm2 before 3.11.7 contains an incorrect authorization vulnerability in the external package allowlist check that uses non-exact substring matching instead of full package-name boundary validation. Attackers can bypass the allowlist by requiring a colliding package name that contains an allowliste...

CVE-2026-92951 vm2 before 3.11.7 Module Allowlist Bypass via Custom Resolver

vm2 before 3.11.7 contains an incorrect authorization vulnerability in the external package allowlist check that uses non-exact substring matching instead of full package-name boundary validation. Attackers can bypass the allowlist by requiring a colliding package name that contains an allowliste...

CVE-2026-92947

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-2026-92933 vm2 before 3.11.8 Information Disclosure via util.getCallSites

vm2 is a sandbox for running untrusted Node.js code. In versions = 22.9 this hands sandboxed code util.getCallSites, a programmatic stack-introspection API that returns the host process's full call stack, including absolute file paths, function names, and line numbers for vm2 bridge internals and...

CVE-2026-92933

vm2 (a Node.js sandbox for untrusted code) in versions ≤ 3.11.7 leaks host-process information to sandboxed code. The root cause is that NodeVM exposes the host util module as an unfiltered shallow copy via defaultBuiltinLoaderUtil, and the deprecated sys builtin (an alias of util) through the ge...

CVE-2026-92933

vm2 is a sandbox for running untrusted Node.js code. In versions = 22.9 this hands sandboxed code "util.getCallSites", a programmatic stack-introspection API that returns the host process's full call stack, including absolute file paths, function names, and line numbers for vm2 bridge internals a...

CVE-2026-86320 Flatpak-builder: host code execution via `git am` hook execution in patch source extraction (`use-git-am`)

A flaw was found in flatpak-builder where Git hooks are not disabled when applying patch sources with use-git-am: true. An attacker who can provide a malicious source containing a Git post-applypatch hook can cause the hook to execute on the host during the build process, resulting in arbitrary...

CVE-2026-86320

CVE-2026-86320 affects flatpak-builder , a build tool for creating Flatpak applications. When applying patch sources with use-git-am: true, Git hooks are not disabled, allowing an attacker who supplies a malicious source containing a post-applypatch hook to execute arbitrary code on the host duri...

kernel: ip6: vti: Use ip6_tnl.net in vti6_siocdevprivate()

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface VTI module. When a VTI tunnel device is moved to a different network environment, an unprivileged user in a separate user space can manipulate tunnel parameters. This manipulation could allow the user to intercept or redirect...

net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

CVE-2026-92942: Uncontrolled Resource Consumption

vm2 before 3.11.7 affected versions = 3.11.6 does not enforce the VM timeout option on code executed outside the synchronous VMrun call. The timeout only wraps the single call to runScript via doWithTimeout in lib/vm.js, and FinalizationRegistry and WeakRef are exposed to sandboxed code unmodifie...

PT-2026-94308

Name of the Vulnerable Software and Affected Versions vm2 versions 3.11.0 through 3.11.6 Description Absolute host filesystem paths are leaked to sandboxed code via error stack formatting. An attacker can force the host-realm source transformer to throw a SyntaxError by calling eval with malforme...

CVE-2026-92938: Protection Mechanism Failure

vm2 versions 3.11.3 through 3.11.6 expose Node.js's host node:sqlite module to code running in NodeVM when that builtin is permitted, either explicitly or through builtin: ''. The module is wrapped with vm.readonly, which prevents property assignment but leaves host-authority callables reachable;...

CVE-2026-92941: Incorrect Permission Assignment for Critical Resource

vm2 versions from 3.11.3 before 3.11.7 expose the host tls module to NodeVM sandbox code, allowing attackers to call tls.setDefaultCACertificates and replace process-wide certificate authorities. Attackers with access to allowed tls and url builtins can use URLSearchParams to create host-realm...

CVE-2026-92953: Improper Control of Dynamically-Managed Code Resources

vm2 versions from 3.11.0 before 3.11.8 fail to protect host TypedArray and ArrayBuffer prototypes from sandbox mutation. Attackers can use prototype-walking primitives to reach and modify host Uint8Array.prototype, %TypedArray%.prototype, and ArrayBuffer.prototype, causing host-created typed arra...
