Overview
Affected versions of this package are vulnerable to Improper Removal of Sensitive Information Before Storage or Transfer via the _sanitizeOptions function in index.js when HTTP headers are supplied as a flat key/value array rather than an object. Because the array form is not converted before sensitive-header filtering is applied, headers designated as sensitive are not recognized and are not stripped on redirect, allowing an attacker in a position to observe outbound requests to capture those header values.
