{"id":"CVE-2023-27485","summary":"Insufficient verification of authorisation when accessing subresults in thmmniii/fbs-core","details":"thmmniii/fbs-core is an open source feedback system for students. In versions prior to 1.5.3 when querying `subresults`, it is possible to query `subresults` from other users due to insufficient authorisation. This is only possible for logged-in users and it is not possible to associate the subresults with a specific user. This bug was fixed in commit `f1ae67d8bb2`and released with version 1.5.3. Users are advised to upgrade. There are no known workarounds for this issue.","aliases":["GHSA-fhq8-p3w6-mmgr"],"modified":"2026-05-17T11:54:20.142712632Z","published":"2023-03-07T18:26:11.365Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/27xxx/CVE-2023-27485.json","cwe_ids":["CWE-863"]},"references":[{"type":"WEB","url":"https://github.com/thm-mni-ii/feedbacksystem/releases/tag/v1.5.3"},{"type":"WEB","url":"https://thm-mni-ii.github.io/feedbacksystem/api-docs/#tag/Submission/operation/getCourseTaskSubmissionSubresults"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/27xxx/CVE-2023-27485.json"},{"type":"ADVISORY","url":"https://github.com/thm-mni-ii/feedbacksystem/security/advisories/GHSA-fhq8-p3w6-mmgr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-27485"},{"type":"FIX","url":"https://github.com/thm-mni-ii/feedbacksystem/commit/f1ae67d8bb2286a8eb15949038473d41b1358493"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
