CVE-2026-63241
An insecure direct object reference vulnerability in Koollab LMS allowed an authenticated user to query the course completion progress of any other user without authorisation, disclosing private learning progress information.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
