{"id":"UBUNTU-CVE-2026-76184","details":"In Eclipse Jetty, HttpClient may receive a redirect of the form: ``` /secure/../evil ``` If an attacker is able to control the redirects, then HttpClient matches authentication credentials against `/secure` rather than normalizing the path to `/evil`, and will therefore follow the redirect sending the `Authorization` header for `/secure` to `/evil`. This also mean that the attacker must have an evil application deployed on the same domain as the target.","modified":"2026-10-28T17:42:49Z","published":"2026-10-15T09:17:00Z","upstream":["CVE-2026-76184"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-76184"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-76184"},{"type":"REPORT","url":"https://github.com/jetty/jetty.project/security/advisories/GHSA-qfr2-43g5-g768"},{"type":"REPORT","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/236"}],"affected":[{"package":{"name":"jetty","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/jetty?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.1.26-1ubuntu1","6.1.26-1ubuntu1.1","6.1.26-1ubuntu1.2"],"ecosystem_specific":{"binaries":[{"binary_version":"6.1.26-1ubuntu1.2","binary_name":"jetty"},{"binary_version":"6.1.26-1ubuntu1.2","binary_name":"libjetty-extra"},{"binary_version":"6.1.26-1ubuntu1.2","binary_name":"libjetty-extra-java"},{"binary_name":"libjetty-java","binary_version":"6.1.26-1ubuntu1.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-76184.json"}},{"package":{"name":"jetty","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/jetty?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.1.26-5","6.1.26-5ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"libjetty-extra","binary_version":"6.1.26-5ubuntu0.1"},{"binary_name":"libjetty-extra-java","binary_version":"6.1.26-5ubuntu0.1"},{"binary_name":"libjetty-java","binary_version":"6.1.26-5ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-76184.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
