{"id":"GHSA-4ww2-rjh2-xpv9","summary":"Duplicate Advisory: Axios: Deep formToJSON Key Recursion Can Cause Denial of Service","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-pmv8-rq9r-6j72. This link is maintained to preserve external references.\n\n## Original Description\naxios 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without appropriate error handling.","modified":"2026-08-31T20:15:05.579084307Z","published":"2026-08-01T15:30:27Z","withdrawn":"2026-08-31T20:02:56Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-08-31T20:02:56Z","nvd_published_at":"2026-08-01T13:17:01Z","cwe_ids":["CWE-400"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/axios/axios/security/advisories/GHSA-pmv8-rq9r-6j72"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67312"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/axios-before-denial-of-service-via-formtojson"}],"affected":[{"package":{"name":"axios","ecosystem":"npm","purl":"pkg:npm/axios"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.0.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-4ww2-rjh2-xpv9/GHSA-4ww2-rjh2-xpv9.json","last_known_affected_version_range":"\u003c 1.18.0"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
