{"id":"DEBIAN-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":"2026-09-02T09:00:42.510586168Z","published":"2026-08-01T13:17:01.407Z","upstream":["CVE-2026-67314"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-67314"}],"affected":[{"package":{"name":"node-axios","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-axios?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.18.0-1"}]}],"versions":["1.11.0+dfsg-1","1.12.1+dfsg-1","1.13.1+dfsg-1","1.13.2+dfsg-1","1.14.0+dfsg-1","1.15.0-1","1.15.2-1","1.16.0-1","1.8.4+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-67314.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"}]}
