{"id":"UBUNTU-CVE-2026-67314","details":"axios versions \u003e=1.15.2 and \u003c1.18.0 contain prototype-pollution read-side gadgets in Basic auth subfield handling (lib/adapters/http.js and lib/helpers/resolveConfig.js). When an application is already affected by a separate prototype-pollution primitive and makes an axios request with an own auth object that omits the username and/or password properties, axios reads the inherited Object.prototype.username and Object.prototype.password values and uses them to construct an outbound 'Authorization: Basic ...' header. axios itself does not pollute prototypes. The practical impact is outbound request tampering: an attacker who controls the polluted prototype values can inject attacker-chosen Basic auth credentials or replace an existing Authorization header. Credential disclosure is only possible under additional application-specific conditions.","modified":"2026-09-03T16:04:44.692500360Z","published":"2026-08-01T13:17:00Z","upstream":["CVE-2026-67314"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-67314"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-67314"},{"type":"REPORT","url":"https://github.com/axios/axios/security/advisories/GHSA-xj6q-8x83-jv6g"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/axios-before-prototype-pollution-via-auth-subfields"}],"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-2026-67314.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-2026-67314.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-2026-67314.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-2026-67314.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:L/VA:L/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"},{"type":"Ubuntu","score":"medium"}]}
