Version Details and Security Vulnerabilities

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 - I used the same solution as CURL did.
2. CVE-2018-1000007.

The package underscore from 1.13.0-0 and before 1.13.0-2, from 1.3.2 and before 1.12.1 are vulnerable to Arbitrary Code Execution via the template function, particularly when a variable property is passed as an argument as it is not sanitized.
