{"id":"CVE-2026-102944","published":"2026-10-14T19:17:06.347","lastModified":"2026-10-16T20:04:29.760","description":"cpp-httplib is a C++ header-only HTTP/HTTPS library. Prior to 0.51.0, create_redirect_client() removes Host, Proxy-Authorization, and Authorization headers when following a cross-origin 301, 302, 307, or 308 redirect but leaves Cookie headers attached. detail::redirect() copies the request for those redirect codes, so cookies supplied directly or through default_headers_ are sent to the redirect target. An attacker who controls a redirect response, or a network position for a non-HTTPS origin, can receive session cookies intended for the original origin. A 303 redirect is not affected because that path clears all request headers. This issue is fixed in version 0.51.0.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-522"],"vendors":[],"products":[],"references":[{"url":"https://github.com/yhirose/cpp-httplib/commit/0c1cc8c9866bb567ff11c1cd0d09779e8c5f8585","tags":[]},{"url":"https://github.com/yhirose/cpp-httplib/releases/tag/v0.51.0","tags":[]},{"url":"https://github.com/yhirose/cpp-httplib/security/advisories/GHSA-22mf-w2v3-r2jv","tags":[]},{"url":"https://github.com/yhirose/cpp-httplib/security/advisories/GHSA-22mf-w2v3-r2jv","tags":[]}],"exploitRefs":[{"url":"https://github.com/yhirose/cpp-httplib/commit/0c1cc8c9866bb567ff11c1cd0d09779e8c5f8585","tags":[]},{"url":"https://github.com/yhirose/cpp-httplib/releases/tag/v0.51.0","tags":[]},{"url":"https://github.com/yhirose/cpp-httplib/security/advisories/GHSA-22mf-w2v3-r2jv","tags":[]},{"url":"https://github.com/yhirose/cpp-httplib/security/advisories/GHSA-22mf-w2v3-r2jv","tags":[]}],"hasPoc":true,"ai":null}
