{"id":"CVE-2023-27485","url":"https://www.cyber-defence.io/tools/cve/CVE-2023-27485","generatedAt":"2026-10-24T22:20:48.918Z","title":"thmmniii/fbs-core is an open source feedback system for students.","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.","published":"2023-03-07T19:15:13.000Z","lastModified":"2026-06-17T05:45:19.000Z","status":"Modified","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"cwe":["CWE-863"],"affected":["thm/feedbacksystem"],"epss":{"score":0.00506,"percentile":0.42362,"date":"2026-10-23","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.51%).
