Executive Summary

This vulnerability in Mahara versions before 22.10.4 and 23.x before 23.04.4 occurs when using the experimental HTML bulk export feature via the administration interface or CLI. The exported files given to account holders may contain images belonging to other account holders because the cache is not cleared after exporting files for one account, leading to unintended information disclosure.

Impact Analysis

The vulnerability can lead to unintended disclosure of images from other users' accounts when exporting data, potentially exposing private or sensitive information to unauthorized account holders.

Mitigation Strategies

To mitigate this vulnerability, avoid using the experimental HTML bulk export feature via the administration interface or CLI until you upgrade to Mahara version 22.10.4 or 23.04.4 or later, where the issue is fixed. Ensure that export files are not shared with account holders until the cache clearing issue is resolved.
