cpp-httplib: cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library
CVE-2026-32627 is fixed in cpp-httplib on 1 platform by DEBIAN-CVE-2026-32627 (version 0.41.0+ds-3), released March 16, 2026. It is not reported as exploited. Patch Radar priority: High.
cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.37.2, when a cpp-httplib client is configured with a proxy and set_follow_location(true), any HTTPS redirect it follows will have TLS certificate and hostname verification silently disabled on the new connection. The client will accept any certificate presented by the redirect target — expired, self-signed, or forged — without raising an error or notifying the application. A network attacker in a position to return a redirect response can fully intercept the follow-up HTTPS connection, including any credentials or session tokens in flight. This vulnerability is fixed in 0.37.2.
