Summary

CVE-2023-48732 is a vulnerability affecting Mattermost, an open-source team communication software. This issue arises due to the failure of Mattermost to properly scope WebSocket responses to individual users. As a result, notifications about new posts to specific users are broadcasted to all members of the channel, potentially revealing sensitive information to unintended recipients. This can lead to privacy breaches and unauthorized access to discussed content. Unpatched Mattermost installations are susceptible to this vulnerability, making it essential for users to update their systems promptly to mitigate the risk.
