It's extremely easy to setup. Just include httplib.h file in your code!\r\n\r\nSecurity Fix(es):\n\ncpp-httplib is a C++ header-only HTTP/HTTPS library. In version 0.49.0, the chunked-response trailer output path writes trailer header names and values directly to the socket without validating them, allowing CRLF sequences in a trailer field to inject additional headers or split the HTTP response. Unlike every other header-writing path in the library, the trailer-writing code applies none of the field-name and field-value checks that reject carriage return and line feed, so an application that places attacker-influenced data into a chunked response trailer emits attacker-controlled CRLF onto the wire. This enables HTTP response splitting, letting an attacker forge response headers or inject a second response. This issue is fixed in version 0.50.0.(CVE-2026-77341)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"cpp-httplib","purl":"pkg:rpm/openEuler/cpp-httplib&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.46.0-3.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["cpp-httplib-0.46.0-3.oe2403sp3.aarch64.rpm","cpp-httplib-debuginfo-0.46.0-3.oe2403sp3.aarch64.rpm","cpp-httplib-debugsource-0.46.0-3.oe2403sp3.aarch64.rpm","cpp-httplib-devel-0.46.0-3.oe2403sp3.aarch64.rpm"],"src":["cpp-httplib-0.46.0-3.oe2403sp3.src.rpm"],"x86_64":["cpp-httplib-0.46.0-3.oe2403sp3.x86_64.rpm","cpp-httplib-debuginfo-0.46.0-3.oe2403sp3.x86_64.rpm","cpp-httplib-debugsource-0.46.0-3.oe2403sp3.x86_64.rpm","cpp-httplib-devel-0.46.0-3.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4093"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77341"}],"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:L/SI:L/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}],"database_specific":{"severity":"Medium"}}
