{"id":"CVE-2023-27485","state":"PUBLISHED","title":"Insufficient verification of authorisation when accessing subresults in thmmniii/fbs-core","description":"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.","publishedAt":"2023-03-07T18:26:11.365Z","updatedAt":"2025-02-25T15:00:16.500Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["thm-mni-ii feedbacksystem"],"affected":[{"vendor":"thm-mni-ii","product":"feedbacksystem","versions":[{"version":"< 1.5.3","status":"affected"}]}],"references":["https://github.com/thm-mni-ii/feedbacksystem/security/advisories/GHSA-fhq8-p3w6-mmgr","https://github.com/thm-mni-ii/feedbacksystem/commit/f1ae67d8bb2286a8eb15949038473d41b1358493","https://github.com/thm-mni-ii/feedbacksystem/releases/tag/v1.5.3","https://thm-mni-ii.github.io/feedbacksystem/api-docs/#tag/Submission/operation/getCourseTaskSubmissionSubresults"],"weaknesses":["CWE-863"],"ingestedAt":"2026-10-29T20:05:52.290Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/27xxx/CVE-2023-27485.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-27485","state":"PUBLISHED","datePublished":"2023-03-07T18:26:11.365Z","dateUpdated":"2025-02-25T15:00:16.500Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-03-01T19:03:56.633Z"},"containers":{"cna":{"title":"Insufficient verification of authorisation when accessing subresults in thmmniii/fbs-core","descriptions":[{"lang":"en","value":"thmmniii/fbs-core is an open source feedback system for students.
