23pds, Chief Information Security Officer of SlowMist, stated on the X platform that curl has fixed 18 security vulnerabilities involving authentication bypass, memory security, and host verification, among which one libcurl vulnerability has existed for about 25 years. Risk affects applications that rely on libcurl SDK、 Containers, firmware, gateways, and CI/CD environments. It is recommended to upgrade curl/libcurl as soon as possible and check if you are using the old version of libcurl, especially focusing on mTLS, proxy authentication, and connection reuse scenarios.
