{"cve":"CVE-2026-67312","nvd":{"published":"2026-08-01T13:17:01.150","modified":"2026-09-01T15:40:58.137","status":"Analyzed","description":"axios versions from 0.28.0 before 0.33.0 and from 1.0.0 before 1.18.0 contain uncontrolled recursion in formDataToJSON (exposed as axios.formToJSON() and used internally when serializing FormData with Content-Type: application/json). When an application passes attacker-controlled FormData field names, a field name with thousands of nested bracket-delimited segments causes unbounded recursion in buildPath(), exhausting the JavaScript call stack (RangeError: Maximum call stack size exceeded) and causing denial of service for that request, or process termination in applications without appropriate error handling.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.3},"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-400"],"references":["https://github.com/axios/axios/security/advisories/GHSA-pmv8-rq9r-6j72","https://www.vulncheck.com/advisories/axios-before-denial-of-service-via-formtojson","https://github.com/axios/axios/security/advisories/GHSA-pmv8-rq9r-6j72"],"products":["axios:axios"],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-67312","score":0.00521,"percentile":0.44267,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-pmv8-rq9r-6j72","url":"https://osv.dev/vulnerability/GHSA-pmv8-rq9r-6j72","summary":"Axios: Deep formToJSON Key Recursion Can Cause Denial of Service","modified":"2026-09-10T03:51:11.689184227Z","packages":[{"ecosystem":"npm","name":"axios","purl":"pkg:npm/axios","ranges":[">=0.28.0 <0.33.0"],"fixed":["0.33.0"]},{"ecosystem":"npm","name":"axios","purl":"pkg:npm/axios","ranges":[">=1.0.0 <1.18.0"],"fixed":["1.18.0"]}]}],"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).
