{"id":"CVE-2020-5231","details":"In Opencast before 7.6 and 8.1, users with the role ROLE_COURSE_ADMIN can use the user-utils endpoint to create new users not including the role ROLE_ADMIN. ROLE_COURSE_ADMIN is a non-standard role in Opencast which is referenced neither in the documentation nor in any code (except for tests) but only in the security configuration. From the name – implying an admin for a specific course – users would never expect that this role allows user creation. This issue is fixed in 7.6 and 8.1 which both ship a new default security configuration.","aliases":["GHSA-94qw-r73x-j7hg"],"modified":"2026-07-09T02:49:27.087393Z","published":"2020-01-30T22:15:10.220Z","references":[{"type":"FIX","url":"https://github.com/opencast/opencast/commit/72fad0031d8a82c860e2bde0b27570c5042320ee"},{"type":"EVIDENCE","url":"https://github.com/opencast/opencast/security/advisories/GHSA-94qw-r73x-j7hg"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opencast/opencast","events":[{"introduced":"0"},{"fixed":"6241ba154a6b364fea1928e52f8bf2a432934dc8"},{"introduced":"5bb6a93a43a7f7c47f789e46e4018c80b8c54c8b"},{"last_affected":"5bb6a93a43a7f7c47f789e46e4018c80b8c54c8b"},{"fixed":"72fad0031d8a82c860e2bde0b27570c5042320ee"}],"database_specific":{"cpe":["cpe:2.3:a:apereo:opencast:*:*:*:*:*:*:*:*","cpe:2.3:a:apereo:opencast:8.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"0"},{"fixed":"7.6"},{"introduced":"8.0"},{"last_affected":"8.0"}],"source":["CPE_RANGE","CPE_STRING","REFERENCES"]}}],"versions":["8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-5231.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
