DATE CVE VULNERABILITY TITLE RISK
2024-08-01 CVE-2024-41162 Unspecified vulnerability in Mattermost Server
Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5 and 9.8.x <= 9.8.1 fail to disallow the modification of local channels by a remote, when shared channels are enabled, which allows a malicious remote to make an arbitrary local channel read-only.

2024-08-01 CVE-2024-41926 Origin Validation Error vulnerability in Mattermost Server
Mattermost versions 9.9.x <= 9.9.0 and 9.5.x <= 9.5.6 fail to validate the source of sync messages and only allow the correct remote IDs, which allows a malicious remote to set arbitrary RemoteId values for synced users and therefore claim that a user was synced from another remote.

2024-04-26 CVE-2024-22091 Allocation of Resources Without Limits or Throttling vulnerability in Mattermost Server
Mattermost versions 8.1.x <= 8.1.10, 9.6.x <= 9.6.0, 9.5.x <= 9.5.2 and 8.1.x <= 8.1.11 fail to limit the size of a request path that includes user inputs which allows an attacker to cause excessive resource consumption, possibly leading to a DoS via sending large request paths

2024-04-26 CVE-2024-32046 Information Exposure Through an Error Message vulnerability in Mattermost Server
Mattermost versions 9.6.x <= 9.6.0, 9.5.x <= 9.5.2, 9.4.x <= 9.4.4 and 8.1.x <= 8.1.11 fail to remove detailed error messages in API requests even if the developer mode is off which allows an attacker to get information about the server such as the full path were files are stored

2024-04-26 CVE-2024-4182 Improper Check for Unusual or Exceptional Conditions vulnerability in Mattermost Server
Mattermost versions 9.6.0, 9.5.x before 9.5.3, 9.4.x before 9.4.5, and 8.1.x before 8.1.12 fail to handle JSON parsing errors in custom status values, which allows an authenticated attacker to crash other users' web clients via a malformed custom status.

2024-04-26 CVE-2024-4183 Allocation of Resources Without Limits or Throttling vulnerability in Mattermost Server
Mattermost versions 8.1.x before 8.1.12, 9.6.x before 9.6.1, 9.5.x before 9.5.3, 9.4.x before 9.4.5 fail 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.

2024-04-26 CVE-2024-4195 Unspecified vulnerability in Mattermost Server
Mattermost versions 9.6.0, 9.5.x before 9.5.3, and 8.1.x before 8.1.12 fail to fully validate role changes, which allows an attacker authenticated as a team admin to promote guests to team admins via crafted HTTP requests.

2024-04-26 CVE-2024-4198 Unspecified vulnerability in Mattermost Server
Mattermost versions 9.6.0, 9.5.x before 9.5.3, and 8.1.x before 8.1.12 fail to fully validate role changes which allows an attacker authenticated as team admin to demote users to guest via crafted HTTP requests.

2024-04-05 CVE-2024-21848 Improper Check for Dropped Privileges vulnerability in Mattermost Server
Improper Access Control in Mattermost Server versions 8.1.x before 8.1.11 allows an attacker that is in a channel with an active call to keep participating in the call even if they are removed from the channel

2024-04-05 CVE-2024-28949 Allocation of Resources Without Limits or Throttling vulnerability in Mattermost Server
Mattermost Server versions 9.5.x before 9.5.2, 9.4.x before 9.4.4, 9.3.x before 9.3.3, 8.1.x before 8.1.11 don't limit the number of user preferences which allows an attacker to send a large number of user preferences potentially causing denial of service.
