{"id":"UBUNTU-CVE-2026-101904","details":"Axios is a promise-based HTTP client for the browser and Node.js. From 1.0.0 until 1.20.0, the dispatchRequest function normalizes inherited Object.prototype.headers from a replacement request configuration. A separate same-process prototype-pollution flaw sets Object.prototype.headers, and trusted request interceptors return a new ordinary configuration without an own headers property. After the interceptor chain, dispatchRequest resolves the inherited headers during normalization. Downstream request processing can observe attacker-controlled headers, including authorization-related values. This issue is fixed in version 1.20.0.","modified":"2026-09-30T21:41:53Z","published":"2026-09-28T18:17:00Z","upstream":["CVE-2026-101904"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-101904"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-101904"},{"type":"REPORT","url":"https://github.com/axios/axios/security/advisories/GHSA-j8rh-479h-cp32"},{"type":"REPORT","url":"https://github.com/axios/axios/pull/11141"},{"type":"REPORT","url":"https://github.com/axios/axios/commit/d19040bda7a8be2f82c3c6e1a5bc03917daee39a"},{"type":"REPORT","url":"https://github.com/axios/axios/releases/tag/v1.20.0"}],"affected":[{"package":{"name":"node-axios","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/node-axios?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.19.0+dfsg-2","0.19.0+dfsg-2ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.19.0+dfsg-2ubuntu0.1~esm1","binary_name":"node-axios"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-101904.json"}},{"package":{"name":"node-axios","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/node-axios?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.21.1+dfsg-1","0.23.0+dfsg-2","0.24.0+dfsg-1","0.25.0+dfsg-2","0.26.0+dfsg-1","0.26.0+dfsg-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.26.0+dfsg-1ubuntu0.1~esm1","binary_name":"node-axios"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-101904.json"}},{"package":{"name":"node-axios","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/node-axios?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.1+dfsg-1","1.5.1+dfsg-1","1.6.2+dfsg-1","1.6.8+dfsg-2","1.6.8+dfsg-2ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.6.8+dfsg-2ubuntu0.1~esm1","binary_name":"node-axios"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-101904.json"}},{"package":{"name":"node-axios","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/node-axios?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.11.0+dfsg-1","1.12.1+dfsg-1","1.13.2+dfsg-1build1","1.13.2+dfsg-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.13.2+dfsg-1ubuntu0.1~esm1","binary_name":"node-axios"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-101904.json"}}],"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:N/SC:L/SI:H/SA:N"},{"type":"Ubuntu","score":"medium"}]}
