High (7.5) in microsoft typed-rest-client. EPSS 2.2% chance of exploitation in the next 30 days. Fixed in typed-rest-client 1.8.0.
typed-rest-client is a library for Node Rest and Http Clients with typings for use with TypeScript. Users of the typed-rest-client library version 1.7.3 or lower are vulnerable to leak authentication data to 3rd parties. The flow of the vulnerability is as follows: First, send any request with `BasicCredentialHandler`, `BearerCredentialHandler` or `PersonalAccessTokenCredentialHandler`. Second, the target host may return a redirection (3xx), with a link to a second host. Third, the next request will use the credentials to authenticate with the second host, by setting the `Authorization` header. The expected behavior is that the next request will *NOT* set the `Authorization` header. The problem was fixed in version 1.8.0. There are no known workarounds.
