Threats affecting pkg:npm/toml-node

CVE-2026-114144 is a high-severity vulnerability in the toml-node library prior to version 5.0.1. It involves uncontrolled resource consumption due to the parsing of unbounded integer digit sequences that are converted to BigInt before range checking. This causes super-linear CPU usage and blocks the Node.js event loop, enabling denial of service via a crafted TOML document. The issue is fixed in version 5.0.1.

CVE-2026-114143 is a high-severity vulnerability in BinaryMuse's toml-node, a TOML parser for Node.js and browsers. Versions prior to 5.0.1 suffer from inefficient algorithmic complexity in handling long dotted keys and table headers, causing quadratic processing time. This can block the Node.js event loop for several seconds and may lead to process termination due to memory exhaustion. The maxDepth option does not mitigate this issue. The vulnerability is fixed in version 5.0.1.

CVE-2026-114142 is a high-severity prototype pollution vulnerability in the toml-node library for Node.js and browsers. Versions prior to 5.0.1 allow attacker-controlled properties to be written to Object.prototype due to improper handling of quoted key paths in the parsing process. This can lead to objects inheriting malicious properties. The issue is fixed in version 5.0.1.

toml-node is a TOML parser for Node.js and the browser. Prior to 5.0.1, the toml.parse() compiler's addTableArray() function in lib/compiler.js rescans the complete assignedPaths and valueAssignments bookkeeping sets for every array-of-tables header. Distinct [[name]] paths are not pruned, so a document with many such headers causes quadratic synchronous work and can block the Node.js event loop, denying service to other operations in the process. This issue is fixed in version 5.0.1.
