CVSS v3.1
Official Description
In Mahara 18.10 before 18.10.5, 19.04 before 19.04.4, and 19.10 before 19.10.2, file metadata information is disclosed to group members in the Elasticsearch result list despite them not having access to that artefact anymore.
Technical Analysis
CVE-2020-9386 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
