Design/Logic Flaw

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 after .ssh/. This misleading documentation affects all users...

Design/Logic Flaw

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 connection, exploiting the lack of limitations on chunk...

CVE-2024-21891

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 vulnerability affects all users using the experiment...

This vulnerability affects all users using the experiment...

CVE-2024-21892

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 CAPNETBINDSERVICE. Due to a bug in the implementation of this exception, Node.js incorrectly applies this...

CVE-2024-21896

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.resolve. By monkey-patching Buffer internals, namely...

CVE-2024-21891

CVE-2024-21891 affects Node.js 20/21 when using the experimental permission model. The issue arises from overwriting built-in path normalization used by node:fs, enabling a filesystem permission model bypass via path traversal. Impact is high (confidentiality/integrity/availability could be affec...

CVE-2024-22019

CVE-2024-22019 affects Node.js HTTP servers. The vulnerability arises from reading an unbounded number of bytes from a single connection due to unbounded chunk extension bytes in chunked encoding, enabling resource exhaustion and DoS. Impact: CPU and network bandwidth exhaustion, bypassing timeou...

CVE-2024-21896

CVE-2024-21896 affects Node.js when using the experimental permission model (Node.js v20/v21). The vulnerability arises from monkey-patching Buffer internals (Buffer.prototype.utf8Write) to modify the result of path.resolve() for user-provided paths, enabling path traversal. Impact is described a...

This vulnerability affects all users using the experiment...

CVE-2024-21892

The CVE-2024-21892 vulnerability affects Node.js on Linux where environment-variable handling with elevated privileges is mishandled due to a buggy exemption; unprivileged users could inject code inheriting the process’s privileges. Connected advisories note Node.js updates/fixes in multiple dist...
