{"id":"CVE-2023-30846","aliases":["GHSA-558p-m34m-vpmq"],"url":"https://o3.security/vulnerability/CVE-2023-30846","summary":"typed-rest-client vulnerable to potential leak of authentication data to 3rd parties","details":"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.","published":"2023-04-26T20:58:02.940Z","modified":"2026-07-15T01:49:08.186684678Z","cvss":{"score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"typed-rest-client","fixedVersion":"1.8.0"}],"fix":{"url":"https://github.com/microsoft/typed-rest-client/commit/f9ff755631b982ee1303dfc3e3c823d0d31233e8","label":"microsoft/typed-rest-client@f9ff755"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/30xxx/CVE-2023-30846.json"},{"type":"ADVISORY","url":"https://github.com/microsoft/typed-rest-client/security/advisories/GHSA-558p-m34m-vpmq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-30846"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20230601-0008/"},{"type":"FIX","url":"https://github.com/microsoft/typed-rest-client/commit/f9ff755631b982ee1303dfc3e3c823d0d31233e8"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:08.186684678Z"}}
