{"id":"CVE-2026-101905","summary":"Axios: Node HTTP adapter prototype-pollution gadget allows request socket hijack via inherited createConnection","details":"Axios is a promise-based HTTP client for the browser and Node.js. From 1.15.2 until 1.20.0, the Node HTTP adapter in lib/adapters/http.js supplies request options without an own createConnection value. A separate same-process prototype-pollution flaw places a function on Object.prototype.createConnection. Node resolves and invokes the inherited createConnection socket factory, allowing the attacker-controlled function to select the transport endpoint. The attacker endpoint can receive request headers and bodies, including credentials, and return attacker-controlled responses while the URL appears legitimate. This issue is fixed in version 1.20.0.","aliases":["GHSA-m8m8-qj5v-23w3"],"modified":"2026-09-30T03:47:02.554397741Z","published":"2026-09-28T17:31:00.916Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-1321","CWE-441"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/101xxx/CVE-2026-101905.json"},"references":[{"type":"WEB","url":"https://github.com/axios/axios/releases/tag/v1.20.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/101xxx/CVE-2026-101905.json"},{"type":"ADVISORY","url":"https://github.com/axios/axios/security/advisories/GHSA-m8m8-qj5v-23w3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-101905"},{"type":"FIX","url":"https://github.com/axios/axios/commit/d19040bda7a8be2f82c3c6e1a5bc03917daee39a"},{"type":"FIX","url":"https://github.com/axios/axios/pull/11141"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/axios/axios","events":[{"introduced":"582934382e4e0e0bcb679c628071a4203e93cf57"},{"fixed":"d19040bda7a8be2f82c3c6e1a5bc03917daee39a"},{"fixed":"84a9f3b9a4f3244b8c8e818f557d64c7b964fb25"}],"database_specific":{"extracted_events":[{"introduced":"1.15.2"},{"fixed":"1.20.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.19.0","v1.18.1","v1.18.0","v1.17.0","v1.16.1","v1.16.0","v1.15.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-101905.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
