Nodejs ≫ Node.Js

The Node.js Permission Model does not clarify in the documentation that wildcards should be only used as the last character of a file path. For example: ``` --allow-fs-read=/home/node/.ssh/*.pub ``` will ignore `pub` and give access to everything a...

Node.js depends on multiple built-in utility functions to normalize paths provided to node:fs functions, which can be overwitten with user-defined implementations leading to filesystem permission model bypass through path traversal attack. This vulne...

On Linux, Node.js ignores certain environment variables if those may have been set by an unprivileged user while the process is running with elevated privileges with the only exception of CAP_NET_BIND_SERVICE. Due to a bug in the implementation of th...

The permission model protects itself against path traversal attacks by calling path.resolve() on any paths given by the user. If the path is to be treated as a Buffer, the implementation uses Buffer.from() to obtain a Buffer from the result of path.r...

A vulnerability in Node.js HTTP servers allows an attacker to send a specially crafted HTTP request with chunked encoding, leading to resource exhaustion and denial of service (DoS). The server reads an unbounded number of bytes from a single connect...

When an invalid public key is used to create an x509 certificate using the crypto.X509Certificate() API a non-expect termination occurs making it susceptible to DoS attacks when the attacker could force interruptions of application processing, as the...

The generateKeys() API function returned from crypto.createDiffieHellman() only generates missing (or outdated) keys, that is, it only generates a private key if none has been set yet, but the function is also needed to compute the corresponding publ...

A vulnerability has been identified in the Node.js (.msi version) installation process, specifically affecting Windows users who install Node.js using the .msi installer. This vulnerability emerges during the repair operation, where the "msiexec.exe"...

The use of __proto__ in process.mainModule.__proto__.require() can bypass the policy mechanism and require modules outside of the policy.json definition. This vulnerability affects all users using the experimental policy mechanism in all active relea...

When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to the node's policy implementation, thus effectively disabling the integrity chec...
