Kerentanan Exposure of Sensitive Information to an Unauthorized Actor pada haxx curl. Skor CVSS 3.1 7.5 (High) menurut CISA ADP.

Deskripsi (NVD)

A vulnerability in libcurl caused the HTTP `Referer:` header to persist even when explicitly cleared. While the documentation states that passing NULL to `CURLOPT_REFERER` suppresses the header, the option failed to clear the internal state. As a result, the previous referrer string was erroneously reused and sent in subsequent requests, potentially leaking sensitive information to unintended servers.
