{"cve":"CVE-2026-77465","nvd":{"published":"2026-09-03T21:17:21.803","modified":"2026-09-09T21:09:13.080","status":"Deferred","description":"toml-node is a TOML parser for Node.js and the browser. Prior to 4.2.0, toml.parse() uses a Peggy 5.1.0 generated recursive-descent parser in lib/parser.js whose peg$parsevalue, peg$parsearray, and peg$parseinline_table_entry functions recurse through nested arrays and inline tables without a depth limit. A remote unauthenticated application parsing an attacker-controlled TOML document containing a few thousand nested arrays or inline tables can exhaust the Node.js call stack, raise an unexpected RangeError rather than the parser's SyntaxError, and terminate an unprotected request worker or process. The corresponding grammar source is src/toml.pegjs, where the generated parser must be bounded. This issue is fixed in version 4.2.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-674"],"references":["https://github.com/BinaryMuse/toml-node/commit/967b8b06754f3ecd9863cea118dc50792a8c353f","https://github.com/BinaryMuse/toml-node/pull/72","https://github.com/BinaryMuse/toml-node/security/advisories/GHSA-82x6-q7mm-w9cf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-77465","score":0.00609,"percentile":0.49181,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-82x6-q7mm-w9cf","url":"https://osv.dev/vulnerability/GHSA-82x6-q7mm-w9cf","summary":"toml-node: Uncontrolled Recursion","modified":"2026-09-03T21:25:36.421557Z","packages":[{"ecosystem":"npm","name":"toml","purl":"pkg:npm/toml","ranges":["<4.2.0"],"fixed":["4.2.0"]}]}],"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).
