Name of the Vulnerable Software and Affected Versions Mattermost versions 8.1.x before 8.1.12 Mattermost versions 9.4.x before 9.4.5 Mattermost versions 9.5.x before 9.5.3 Mattermost versions 9.6.x before 9.6.1

Description The issue is related to the failure to limit the number of active sessions, which allows an authenticated attacker to crash the server via repeated requests to the "getSessions API" after flooding the sessions table.

Recommendations For versions 8.1.x before 8.1.12, update to version 8.1.12 or later. For versions 9.4.x before 9.4.5, update to version 9.4.5 or later. For versions 9.5.x before 9.5.3, update to version 9.5.3 or later. For versions 9.6.x before 9.6.1, update to version 9.6.1 or later. As a temporary workaround, consider restricting access to the "getSessions API" to minimize the risk of exploitation.
