{"id":"UBUNTU-CVE-2026-44489","details":"Axios is a promise based HTTP client for the browser and Node.js. From 1.15.2 to before 1.16.0, nested objects created by utils.merge() (e.g., config.proxy) are still constructed as plain {} with Object.prototype in their chain. The setProxy() function at lib/adapters/http.js:209-223 reads proxy.username, proxy.password, and proxy.auth without hasOwnProperty checks. When Object.prototype.username is polluted, setProxy() constructs a Proxy-Authorization header with attacker-controlled credentials and injects it into every proxied HTTP request. This vulnerability is fixed in 1.16.0.","modified":"2026-08-14T01:19:49.336729734Z","published":"2026-06-11T17:16:00Z","upstream":["CVE-2026-44489"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-44489"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-44489"},{"type":"REPORT","url":"https://github.com/axios/axios/security/advisories/GHSA-654m-c8p4-x5fp"}],"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-2026-44489.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-2026-44489.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-2026-44489.json"}},{"package":{"name":"node-axios","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/node-axios?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.7.9+dfsg-1","1.8.4+dfsg-1","1.11.0+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-axios","binary_version":"1.11.0+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-44489.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-2026-44489.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
