{"id":"DEBIAN-CVE-2026-44681","details":"Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.6.12 and 1.7.1, an unauthenticated open redirect in Authlib's OpenIDImplicitGrant and OpenIDHybridGrant authorization endpoint lets a remote attacker cause the authorization server to issue an HTTP 302 to an attacker-chosen URL by submitting an authorization request that omits the openid scope. This vulnerability is fixed in 1.6.12 and 1.7.1.","modified":"2026-09-01T16:06:44.868180166Z","published":"2026-05-27T20:16:37.463Z","upstream":["CVE-2026-44681"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-44681"}],"affected":[{"package":{"name":"python-authlib","ecosystem":"Debian:12","purl":"pkg:deb/debian/python-authlib?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.0-1+deb12u2"}]}],"versions":["1.2.0-1","1.2.0-1+deb12u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44681.json"}},{"package":{"name":"python-authlib","ecosystem":"Debian:13","purl":"pkg:deb/debian/python-authlib?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.0-1","1.6.0-1+deb13u1","1.6.1-1","1.6.3-1","1.6.4-1","1.6.5-1","1.6.6-1","1.6.7-1","1.6.8-1","1.6.9-1","1.7.0-1","1.7.2-1","1.7.2-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44681.json"}},{"package":{"name":"python-authlib","ecosystem":"Debian:14","purl":"pkg:deb/debian/python-authlib?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.7.2-1"}]}],"versions":["1.6.0-1","1.6.1-1","1.6.3-1","1.6.4-1","1.6.5-1","1.6.6-1","1.6.7-1","1.6.8-1","1.6.9-1","1.7.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44681.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
