{"id":"UBUNTU-CVE-2026-101902","details":"Axios is a promise-based HTTP client for the browser and Node.js. From 0.27.2 until 0.34.0 and 1.20.0, Axios default-instance requests that omit an explicit method can read an inherited method value from Object.prototype. If another vulnerability in the same process pollutes Object.prototype.method, calls such as axios.request({ url }) and axios({ url }) can send a state-changing HTTP method instead of the expected default GET. Axios does not create the prototype pollution source. This is a read-side gadget in axios request dispatch. This issue is fixed in version 0.34.0 and 1.20.0.","modified":"2026-09-29T23:41:14.656811245Z","published":"2026-09-29T00:00:00Z","upstream":["CVE-2026-101902"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-101902"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-101902"},{"type":"REPORT","url":"https://github.com/axios/axios/security/advisories/GHSA-9fr6-4gfg-395g"},{"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/v0.34.0"},{"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_name":"node-axios","binary_version":"0.19.0+dfsg-2ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-101902.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-2026-101902.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_name":"node-axios","binary_version":"1.6.8+dfsg-2ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-101902.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_name":"node-axios","binary_version":"1.13.2+dfsg-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-101902.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:N/SI:H/SA:N"},{"type":"Ubuntu","score":"medium"}]}
