{"id":"DEBIAN-CVE-2026-111755","details":"follow-redirects is a Node.js HTTP and HTTPS client wrapper that automatically follows redirects. From 1.16.0 until 1.16.1, escapeRegex leaves valid header-name metacharacters unescaped in sensitiveHeaders. When an application declares a sensitive header whose name contains ^ or | and follows a cross-origin or HTTPS-to-HTTP redirect, unescaped regular-expression metacharacters prevent the generated filter from matching the declared header name, and the credential header is forwarded to an attacker-controlled redirect target. This issue is fixed in version 1.16.1.","modified":"2026-10-30T10:01:35.808972284Z","published":"2026-10-19T18:17:00.260Z","upstream":["CVE-2026-111755"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-111755"}],"affected":[{"package":{"name":"node-follow-redirects","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-follow-redirects?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.15.11+~1.14.4-1","1.15.11+~1.14.4-2","1.15.2+~1.14.1-1","1.15.3+~1.14.2-1","1.15.6+~1.14.4-1","1.15.6+~1.14.4-2","1.15.9+~1.14.4-1","1.16.0+~1.14.4-1","1.16.0+~1.14.4-2","1.16.1+~1.14.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-111755.json"}},{"package":{"name":"node-follow-redirects","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-follow-redirects?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.15.11+~1.14.4-1","1.15.11+~1.14.4-2","1.15.9+~1.14.4-1","1.16.0+~1.14.4-1","1.16.0+~1.14.4-2","1.16.1+~1.14.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-111755.json"}},{"package":{"name":"node-follow-redirects","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-follow-redirects?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.16.1+~1.14.4-1"}]}],"versions":["1.15.11+~1.14.4-1","1.15.11+~1.14.4-2","1.15.9+~1.14.4-1","1.16.0+~1.14.4-1","1.16.0+~1.14.4-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-111755.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/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"}]}
