# Skuul School Management System: students can read other students' exam results

Skuul School Management System through version 2.6.5 has an access control flaw in its ResultChecker::checkResult method. A logged-in student can change the studentId parameter to view another student's examination results and marks.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Confirm whether the deployment runs Skuul School Management System and its version, which is `2.6.5` or earlier if affected
- Review whether the result-checking function enforces that the requested studentId matches the logged-in user (unknown from the sources)
