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.","state":0,"publishedAt":"2026-10-14T18:18:21.598+00:00","modifiedAt":"2026-10-15T14:48:03.087+00:00","affected":[{"ecosystem":"Vendor product","name":"cpp-httplib","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"yhirose\",\n                    \"product\": \"cpp-httplib\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.51.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://github.com/yhirose/cpp-httplib/security/advisories/GHSA-22mf-w2v3-r2jv","https://github.com/yhirose/cpp-httplib/commit/0c1cc8c9866bb567ff11c1cd0d09779e8c5f8585","https://github.com/yhirose/cpp-httplib/releases/tag/v0.51.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102944","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102944","identifiers":["CVE-2026-102944"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
