**Name of the Vulnerable Software and Affected Versions** Quassel IRC versions prior to 0.9.2 **Description** The issue allows remote authenticated users to read other users' backlogs due to improper verification of the user ID when accessing user backlogs. This is related to the `bufferid` in SQL queries. **Recommendations** For versions prior to 0.9.2, update to version 0.9.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the bufferid in SQL queries to minimize the risk of exploitation.
