This critical-severity CVE scores 9.1 under NVD CVSS v3. EPSS exploit probability: 2.2%, top 19% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
