NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-std-static package and not the rust-std-static package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
