CVE-2023-27485

Date: March 7, 2023

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.
