If a host application is already affected by prototype pollution and then makes an axios request with an own `auth` object that omits `username` or `password`, axios reads inherited `Object.prototype.username` and `Object.prototype.password` values and uses them to construct an outbound `Authorization: Basic ...` header.\n\nThis does not mean axios itself pollutes prototypes. Exploitation requires a separate prototype-pollution primitive in the host process, plus an axios call pattern such as `auth: opts.auth || {}`.\n\n## Impact\n\nAn attacker who can pollute `Object.prototype.username` and/or `Object.prototype.password` can influence the Basic auth header on affected axios requests that pass an empty or partial own `auth` object.\n\nThe practical impact is outbound request tampering. The attacker can inject attacker-chosen Basic auth credentials, replace an existing `Authorization` header because axios removes it when `auth` is used, or cause downstream authorization failures.\n\nThis should not be described as automatic credential exfiltration","public_affected_ranges":[">= 1.15.2, < 1.18.0"]}],"null_published_at":"2026-11-03T10:03:26.567Z","source_updated_at":"2026-08-07T17:52:12.000Z","source_disclosed_at":"2026-07-20T17:51:17.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-03T02:28:46.523Z"}],"next_cursor":null,"snapshot_revision":"42594"}
