{"id":"UBUNTU-CVE-2026-82467","details":"Rodauth before 2.47.0 fails to validate protocol-relative return-to paths in confirm_password, login_return_to_requested_location, and two_factor_auth_return_to_requested_location features. Attackers can craft paths with leading double slashes that browsers resolve as protocol-relative URLs, redirecting authenticated users to attacker-controlled sites after login or password confirmation.","modified":"2026-10-17T13:01:11.335810555Z","published":"2026-08-29T17:17:00Z","upstream":["CVE-2026-82467"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-82467"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-82467"},{"type":"REPORT","url":"https://github.com/jeremyevans/rodauth/security/advisories/GHSA-h9m4-vm9w-h43m"},{"type":"REPORT","url":"https://github.com/jeremyevans/rodauth"},{"type":"REPORT","url":"https://github.com/jeremyevans/rodauth/commit/295044a92e358479afdf84f905dd5efe89c39aea"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/rodauth-before-2.47.0-open-redirect-via-return-to-path"}],"affected":[{"package":{"name":"ruby-rodauth","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/ruby-rodauth?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.43.0-1","2.44.0-1","2.45.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"ruby-rodauth","binary_version":"2.45.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-82467.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
