Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.

Changing a captured POST request to a GET request against the /rest/v1/course PostgREST endpoint results in disclosure of sensitive information including other students details, tutor/admin profiles, and internal course metadata.
