libcurl vulnerability

About this tag
The libcurl vulnerability tag covers disclosed security issues in the libcurl library, which is widely embedded in software including Windows components and Azure Linux. Recent discussions focus on CVE-2026-7168, a medium-severity flaw where a reused libcurl handle can leak Digest Proxy-Authorization headers between different HTTP proxies, and CVE-2023-27535, which involves FTP connection reuse with incorrect credentials. For Windows administrators, these vulnerabilities matter because curl is part of the platform's plumbing and libcurl is often hidden inside applications. The tag emphasizes inventory, proxy hygiene, and understanding that not all vulnerabilities are remote-code-execution emergencies, but they require careful patching and configuration review.
