CVE-2026-47683

A flaw was found in vm2, an open-source virtual machine VM sandbox for Node.js. This vulnerability allows malicious code running within the sandbox to bypass the configured memory allocation limit. By crafting specific calls to Buffer.concat or Buffer.from with attacker-controlled lengths, the...

SUSE CVE-2026-86472

fast-uri is a dependency-free RFC 3986 URI parser for Node.js, used by Fastify and ajv. In versions before 2.4.7, from 3.0.0 through 3.1.7, and from 4.0.0 through 4.1.4, fast-uri folds the host to lowercase before it percent-decodes the host, so a percent-encoded uppercase octet such as %41 decod...

SUSE CVE-2026-86818

fast-uri is a dependency-free RFC 3986 URI parser for Node.js, used by Fastify and ajv, that added a mailto scheme parser in version 4.1.3. In versions 4.1.3 and 4.1.4, the mailto parser compares each query field name to the reserved names to, subject, and body while the name is still...

ExifReader: DoS via Crafted HEIC/AVIF iloc Box - Memory Exhaustion

Summary ExifReader 4.41.0 is vulnerable to denial of service through a crafted HEIC or AVIF file with a malicious iloc box. When offsetSize, lengthSize, and baseOffsetSize are set to zero in the iloc header, the extent-parsing loop allocates an unbounded number of JavaScript objects - up to...

Summary ExifReader 4.41.0 is vulnerable to denial of service through a crafted HEIC or AVIF file with a malicious iloc box. When offsetSize, lengthSize, and baseOffsetSize are set to zero in the iloc header, the extent-parsing loop allocates an unbounded number of JavaScript objects - up to...

CVE-2026-85715

ExifReader is a JavaScript Exif information parser. Prior to 4.41.1, ExifReader parses attacker-controlled HEIC or AVIF ISO-BMFF files in getItems within src/image-header-iso-bmff-iloc.js and trusts iloc itemCount and extentCount values while allocating an extent object for every nested-loop...

CVE-2026-92958

A flaw was found in vm2, a sandbox for Node.js. When the NodeVM embedder uses a builtin wildcard with negative entries to deny specific modules, such as 'fs' for file system access, the denylist mechanism fails to block subpaths like 'fs/promises'. This allows sandboxed code to bypass the intende...

Information Exposure

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Information Exposure in the util.getCallSites function. An attacker can access sensitive information from the host environment, such as absolute file...

Exposure of Resource to Wrong Sphere

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Exposure of Resource to Wrong Sphere in the globalAgent process. An attacker can access sensitive HTTPS credentials and intercept or manipulate...

Protection Mechanism Failure

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Protection Mechanism Failure in the Promise.prototype.finally process. An attacker can execute arbitrary code by crafting an async function that...

Incorrect Resource Transfer Between Spheres

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Incorrect Resource Transfer Between Spheres incomplete filtering of Node.js registered internal symbols across the sandbox boundary. An attacker can...

Protection Mechanism Failure

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Protection Mechanism Failure via the WebAssembly.compileStreaming and WebAssembly.instantiateStreaming functions. An attacker can gain access to the...

Uncaught Exception

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Uncaught Exception in the handling of Promises returned from the host realm into the sandbox. An attacker can cause the host process to terminate...

Improper Privilege Management

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Improper Privilege Management in the require process. An attacker can execute arbitrary commands on the host system by bypassing the intended module...

Protection Mechanism Failure

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Protection Mechanism Failure through improper enforcement of the allowAsync option in the VM and NodeVM. An attacker can execute code asynchronously...

Process Control

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Process Control in the crypto.setEngine function. An attacker can execute arbitrary native code in the host process by supplying a path to a maliciou...
