{"id":"UBUNTU-CVE-2026-116689","details":"follow-redirects is a Node.js HTTP and HTTPS client wrapper that automatically follows redirects. From 1.16.0 until 1.16.2, the documented sensitiveHeaders option is checked with value instanceof Array, so an array created in another JavaScript realm is replaced with an empty list even though Array.isArray recognizes it. When a request then follows an attacker-controlled cross-origin redirect, a custom credential header named in that discarded list can be forwarded to the redirect destination. This issue is fixed in version 1.16.2.","modified":"2026-10-28T20:17:45.942941991Z","published":"2026-10-27T20:17:00Z","upstream":["CVE-2026-116689"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-116689"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-116689"},{"type":"REPORT","url":"https://github.com/follow-redirects/follow-redirects/security/advisories/GHSA-mrwp-f3q8-3g9p"},{"type":"REPORT","url":"https://github.com/follow-redirects/follow-redirects/commit/b0a7751e9cd64cd8eeb6ec67d2f206a9cc88d3f8"},{"type":"REPORT","url":"https://github.com/follow-redirects/follow-redirects/releases/tag/v1.16.2"}],"affected":[{"package":{"name":"node-follow-redirects","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/node-follow-redirects?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.4-1","1.2.4-1ubuntu0.18.04.1~esm1","1.2.4-1ubuntu0.18.04.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.4-1ubuntu0.18.04.1~esm2","binary_name":"node-follow-redirects"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116689.json"}},{"package":{"name":"node-follow-redirects","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/node-follow-redirects?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.4-1","1.2.4-1ubuntu0.20.04.1~esm1","1.2.4-1ubuntu0.20.04.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.4-1ubuntu0.20.04.1~esm2","binary_name":"node-follow-redirects"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116689.json"}},{"package":{"name":"node-follow-redirects","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/node-follow-redirects?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.13.1-1","1.14.5-1","1.14.7+~1.13.1-1","1.14.8+~1.14.0-1","1.14.9+~1.14.1-1","1.14.9+~1.14.1-1ubuntu0.1~esm1","1.14.9+~1.14.1-1ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"node-follow-redirects","binary_version":"1.14.9+~1.14.1-1ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116689.json"}},{"package":{"name":"node-follow-redirects","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/node-follow-redirects?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.15.2+~1.14.1-1","1.15.3+~1.14.2-1","1.15.6+~1.14.4-1","1.15.6+~1.14.4-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-follow-redirects","binary_version":"1.15.6+~1.14.4-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116689.json"}},{"package":{"name":"node-follow-redirects","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/node-follow-redirects?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.15.11+~1.14.4-1build1","1.16.0+~1.14.4-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.16.0+~1.14.4-2","binary_name":"node-follow-redirects"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116689.json"}},{"package":{"name":"node-follow-redirects","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/node-follow-redirects?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.15.9+~1.14.4-1","1.15.11+~1.14.4-1build1","1.15.11+~1.14.4-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-follow-redirects","binary_version":"1.15.11+~1.14.4-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116689.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
