{"id":"DEBIAN-CVE-2026-91766","details":"When the http:// stream wrapper follows a redirect it forwards the user-supplied Authorization, Cookie and Proxy-Authorization headers unchanged, even when the redirect target is a different host, a different port, or a downgrade from HTTPS to HTTP. A server that can steer a redirect therefore receives credentials that were only meant for the original origin. This is the same class of issue that libcurl fixed in 7.58.0 ( CVE-2018-1000007 https://github.com/advisories/GHSA-g7x2-hrfp-pv5f ).","modified":"2026-09-26T05:01:19.410469363Z","published":"2026-09-25T21:17:24.673Z","upstream":["CVE-2026-91766"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-91766"}],"affected":[{"package":{"name":"php8.2","ecosystem":"Debian:12","purl":"pkg:deb/debian/php8.2?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.2.10-1","8.2.10-2","8.2.12-1","8.2.16-1","8.2.16-2","8.2.17-1","8.2.18-1","8.2.18-1~deb12u1","8.2.20-1~deb12u1","8.2.20-2","8.2.20-3","8.2.21-1","8.2.23-1","8.2.24-1","8.2.24-1~deb12u1","8.2.26-1~deb12u1","8.2.26-4","8.2.27-1","8.2.28-1~deb12u1","8.2.29-1~deb12u1","8.2.30-1~deb12u1","8.2.31-1~deb12u1","8.2.32-1~deb12u1","8.2.33-1~deb12u1","8.2.5-2","8.2.7-1","8.2.7-1.1","8.2.7-1.2","8.2.7-1~deb12u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-91766.json"}},{"package":{"name":"php8.4","ecosystem":"Debian:13","purl":"pkg:deb/debian/php8.4?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.4.26-1~deb13u1"}]}],"versions":["8.4.11-1","8.4.16-1","8.4.16-1~deb13u1","8.4.20-1","8.4.21-1","8.4.21-1~deb13u1","8.4.22-1","8.4.23-1","8.4.23-1~deb13u1","8.4.24-1","8.4.24-1~deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-91766.json"}},{"package":{"name":"php8.4","ecosystem":"Debian:14","purl":"pkg:deb/debian/php8.4?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.4.11-1","8.4.16-1","8.4.16-1~deb13u1","8.4.20-1","8.4.21-1","8.4.21-1~deb13u1","8.4.22-1","8.4.23-1","8.4.23-1~deb13u1","8.4.24-1","8.4.24-1~deb13u1","8.4.26-1~deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-91766.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
