{"id":"UBUNTU-CVE-2026-54605","details":"OAuth is a Ruby wrapper for the OAuth 1.0 and 1.0a protocols, providing clients and servers. From 0.5.5 to 1.1.5, OAuth::Consumer#token_request parses the raw Location header of a 300 to 399 redirect returned by the OAuth server and follows the redirect recursively, which can mutate the consumer's configuration and expose signed OAuth request metadata, including the Authorization header, to a cross-origin host. This issue is fixed in version 1.1.6.","modified":"2026-08-06T03:10:20.915462066Z","published":"2026-07-28T17:16:00Z","upstream":["CVE-2026-54605"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-54605"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-54605"},{"type":"REPORT","url":"https://github.com/ruby-oauth/oauth/security/advisories/GHSA-prq8-7wvh-44qh"}],"affected":[{"package":{"name":"ruby-oauth","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/ruby-oauth?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.4.7-3"],"ecosystem_specific":{"binaries":[{"binary_version":"0.4.7-3","binary_name":"ruby-oauth"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54605.json"}},{"package":{"name":"ruby-oauth","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/ruby-oauth?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.5.3-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.5.3-1","binary_name":"ruby-oauth"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54605.json"}},{"package":{"name":"ruby-oauth","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/ruby-oauth?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.5.4-1"],"ecosystem_specific":{"binaries":[{"binary_name":"ruby-oauth","binary_version":"0.5.4-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54605.json"}},{"package":{"name":"ruby-oauth","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/ruby-oauth?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.5.4-1.1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.5.4-1.1","binary_name":"ruby-oauth"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54605.json"}},{"package":{"name":"ruby-oauth","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/ruby-oauth?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.5.4-1.1"],"ecosystem_specific":{"binaries":[{"binary_name":"ruby-oauth","binary_version":"0.5.4-1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54605.json"}},{"package":{"name":"ruby-oauth","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/ruby-oauth?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.5.4-1.1"],"ecosystem_specific":{"binaries":[{"binary_name":"ruby-oauth","binary_version":"0.5.4-1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-54605.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
