{"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":"2026-08-12T03:51:12.828525011Z","published":"2023-03-07T18:26:11.365Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/27xxx/CVE-2023-27485.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/thm-mni-ii/feedbacksystem","events":[{"introduced":"0"},{"fixed":"9f9341f765264d4389e1a5b36d97be363bed0f14"},{"fixed":"f1ae67d8bb2286a8eb15949038473d41b1358493"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:thm:feedbacksystem:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.5.3"}]}}],"versions":["v1.5.2","v1.5.1","v1.5.0","v1.4.2","v1.4.1","v1.4.0","v1.3.0","v1.2.1","v1.2.0","v1.1.1","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-27485.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
