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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-863"],"references":["https://github.com/thm-mni-ii/feedbacksystem/commit/f1ae67d8bb2286a8eb15949038473d41b1358493","https://github.com/thm-mni-ii/feedbacksystem/releases/tag/v1.5.3","https://github.com/thm-mni-ii/feedbacksystem/security/advisories/GHSA-fhq8-p3w6-mmgr","https://thm-mni-ii.github.io/feedbacksystem/api-docs/#tag/Submission/operation/getCourseTaskSubmissionSubresults","https://github.com/thm-mni-ii/feedbacksystem/commit/f1ae67d8bb2286a8eb15949038473d41b1358493"],"products":["thm:feedbacksystem"],"source":"nvd","synced_at":"2026-10-19T21:37:41.955480748+00:00"},"epss":{"cve":"CVE-2023-27485","score":0.00506,"percentile":0.43253,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
