{"cve":"CVE-2026-67318","nvd":{"published":"2026-08-01T13:17:01.947","modified":"2026-09-01T15:39:49.073","status":"Analyzed","description":"axios versions >=1.13.0 (Node.js HTTP adapter) fail to enforce the configured maxBodyLength limit on streamed request bodies when requests are sent with httpVersion: 2. Because Node's HTTP/2 request API does not honor the maxBodyLength option and axios's byte-counting stream wrapper is gated on maxRedirects === 0, an attacker who controls a stream passed to axios can cause the application to transmit outbound data exceeding the configured finite maxBodyLength. Impact is limited to resource consumption and policy bypass (excess egress, upstream quota consumption, limited availability); it does not enable code execution, credential disclosure, or request-destination control. Calls using the default maxBodyLength: -1 and browser adapters are not affected.","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:L","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:L","score":5.3},"cwes":["CWE-400"],"references":["https://github.com/axios/axios/security/advisories/GHSA-mwf2-3pr3-8698","https://www.vulncheck.com/advisories/axios-before-maxbodylength-bypass-via-http-2","https://github.com/axios/axios/security/advisories/GHSA-mwf2-3pr3-8698"],"products":["axios:axios"],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-67318","score":0.00616,"percentile":0.49543,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-mwf2-3pr3-8698","url":"https://osv.dev/vulnerability/GHSA-mwf2-3pr3-8698","summary":"Axios: HTTP/2 streamed uploads bypass `maxBodyLength`","modified":"2026-09-10T03:50:12.260991190Z","packages":[{"ecosystem":"npm","name":"axios","purl":"pkg:npm/axios","ranges":[">=1.13.0 <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).
