Sources and claim methodology

Upstream source description

### Impact Users of 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: 1. Send any request with `BasicCredentialHandler`, `BearerCredentialHandler` or `PersonalAccessTokenCredentialHandler` 2. The target host may return a redirection (3xx), with a link to a second host. 3. 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. ### Patches The problem was fixed on April 1st 2020. ### Workarounds There is no workaround. ### References This is similar to the following issues in nature: 1. [HTTP authentication leak in redirects](https://curl.haxx.se/docs/CVE-2018-1000007.html) - I used the same solution as CURL did. 2. [CVE-2018-1000007](https://nvd.nist.gov/vuln/detail/CVE-2018-1000007).
