{"cve":"CVE-2026-114143","nvd":{"published":"2026-10-21T21:17:56.963","modified":"2026-10-22T16:48:25.420","status":"Deferred","description":"toml-node is a TOML parser for Node.js and the browser. Prior to 5.0.1, toml.parse() repeatedly slices and rejoins every path prefix in lib/compiler.js while processing long dotted keys, table headers, array-of-tables headers, and inline-table keys in assign(), deepRef(), and setNestedKey(). The resulting quadratic work can block the Node.js event loop for several seconds, and sufficiently long paths can terminate the process through memory exhaustion. The maxDepth option does not limit key-segment count and therefore does not mitigate this path. This issue is fixed in version 5.0.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-407"],"references":["https://github.com/BinaryMuse/toml-node/commit/609c873fffea0a27ebe5b4dd098eed2b3daf3606","https://github.com/BinaryMuse/toml-node/releases/tag/v5.0.1","https://github.com/BinaryMuse/toml-node/security/advisories/GHSA-9j65-hcg3-gc64"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-114143","score":0.00365,"percentile":0.30141,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-9j65-hcg3-gc64","url":"https://osv.dev/vulnerability/GHSA-9j65-hcg3-gc64","summary":"toml-node: Quadratic-complexity DoS via long dotted keys or table paths in toml.parse()","modified":"2026-10-22T16:45:03.729593661Z","packages":[{"ecosystem":"npm","name":"toml","purl":"pkg:npm/toml","ranges":["<5.0.1"],"fixed":["5.0.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
