{"id":"UBUNTU-CVE-2026-102944","details":"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.","modified":"2026-10-17T12:57:57.403442828Z","published":"2026-10-15T00:00:00Z","upstream":["CVE-2026-102944"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-102944"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-102944"},{"type":"REPORT","url":"https://github.com/yhirose/cpp-httplib/commit/0c1cc8c9866bb567ff11c1cd0d09779e8c5f8585"},{"type":"REPORT","url":"https://github.com/yhirose/cpp-httplib/releases/tag/v0.51.0"},{"type":"REPORT","url":"https://github.com/yhirose/cpp-httplib/security/advisories/GHSA-22mf-w2v3-r2jv"}],"affected":[{"package":{"name":"cpp-httplib","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/cpp-httplib?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.9+ds-1","0.9.10+ds-1","0.10.1+ds-1","0.10.2+ds-1","0.10.3+ds-1","0.10.3+ds-1ubuntu0.1~esm1","0.10.3+ds-1ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"libcpp-httplib0","binary_version":"0.10.3+ds-1ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102944.json"}},{"package":{"name":"cpp-httplib","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/cpp-httplib?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.13.1+ds-1ubuntu1","0.14.3+ds-1","0.14.3+ds-1.1","0.14.3+ds-1.1build1","0.14.3+ds-1.1build2","0.14.3+ds-1.1ubuntu0.1~esm1","0.14.3+ds-1.1ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"libcpp-httplib0.14t64","binary_version":"0.14.3+ds-1.1ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102944.json"}},{"package":{"name":"cpp-httplib","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/cpp-httplib?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.26.0+ds-2ubuntu3","0.26.0+ds-2ubuntu4"],"ecosystem_specific":{"binaries":[{"binary_name":"libcpp-httplib0.26","binary_version":"0.26.0+ds-2ubuntu4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102944.json"}},{"package":{"name":"cpp-httplib","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/cpp-httplib?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.18.7-1","0.26.0+ds-2ubuntu2","0.26.0+ds-2ubuntu3","0.26.0+ds-2ubuntu3+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.26.0+ds-2ubuntu3+esm1","binary_name":"libcpp-httplib0.26"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102944.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
