CVE-2026-114141 · toml-node: Quadratic-complexity DoS via many array-of-tables headers in toml.parse()

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
