Vulnerability from cvelistv5 – Published: 2025-02-14 17:52 – Updated: 2025-02-14 18:09

Title

Leaked User IDs and Metadata of Deleted DMs

Summary

Mattermost versions 9.11.x <= 9.11.6 fail to filter out DMs from the deleted channels endpoint which allows an attacker to infer user IDs and other metadata from deleted DMs if someone had manually marked DMs as deleted in the database.

Severity
