Resource Exhaustion in Mattermost Server versions 8.1.x before 8.1.10 fails to limit the size of the payload that can be read and parsed allowing an attacker to send a very large email payload and crash the server.
CVE-2024-2446 1 Mattermost 1 Mattermost Server 2024-12-13 N/A 4.3 MEDIUM

CVE-2024-2450 1 Mattermost 1 Mattermost Server 2024-12-13 N/A 8.8 HIGH
Mattermost versions 8.1.x before 8.1.10, 9.2.x before 9.2.6, 9.3.x before 9.3.2, and 9.4.x before 9.4.3 fail to correctly verify account ownership when switching from email to SAML authentication, allowing an authenticated attacker to take over other user accounts via a crafted switch request under specific conditions.
CVE-2024-21848 1 Mattermost 1 Mattermost Server 2024-12-13 N/A 3.1 LOW
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
CVE-2024-29221 1 Mattermost 1 Mattermost Server 2024-12-13 N/A 4.7 MEDIUM
Improper Access Control in 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 lacked proper access control in the `/api/v4/users/me/teams` endpoint allowing a team admin to get the invite ID of their team, thus allowing them to invite users, even if the "Add Members" permission was explicitly removed from team admins.
CVE-2024-2447 1 Mattermost 1 Mattermost Server 2024-12-13 N/A 6.5 MEDIUM
Mattermost versions 8.1.x before 8.1.11, 9.3.x before 9.3.3, 9.4.x before 9.4.4, and 9.5.x before 9.5.2 fail to authenticate the source of certain types of post actions, allowing an authenticated attacker to create posts as other users via a crafted post action.
CVE-2024-28949 1 Mattermost 1 Mattermost Server 2024-12-12 N/A 4.3 MEDIUM
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.
CVE-2024-6428 1 Mattermost 1 Mattermost 2024-11-21 N/A 5.3 MEDIUM
Mattermost versions 9.8.0, 9.7.x <= 9.7.4, 9.6.x <= 9.6.2, 9.5.x <= 9.5.5 fail to prevent specifying a RemoteId when creating a new user which allows an attacker to specify both a remoteId and the user ID, resulting in creating a user with a user-defined user ID. This can cause some broken functionality in User Management such administrative actions against the user not working.
CVE-2024-39830 1 Mattermost 1 Mattermost 2024-11-21 N/A 8.1 HIGH
Mattermost versions 9.8.x <= 9.8.0, 9.7.x <= 9.7.4, 9.6.x <= 9.6.2 and 9.5.x <= 9.5.5, when shared channels are enabled, fail to use constant time comparison for remote cluster tokens which allows an attacker to retrieve the remote cluster token via a timing attack during remote cluster token comparison.
CVE-2024-39807 1 Mattermost 1 Mattermost 2024-11-21 N/A 3.1 LOW
Mattermost versions 9.5.x <= 9.5.5 and 9.8.0 fail to properly sanitize the recipients of a webhook event which allows an attacker monitoring webhook events to retrieve the channel IDs of archived or restored channels.
CVE-2024-39767 1 Mattermost 1 Mattermost Mobile 2024-11-21 N/A 4.2 MEDIUM
Mattermost Mobile Apps versions <=2.16.0 fail to validate that the push notifications received for a server actually came from this serve that which allows a malicious server to send push notifications with another server’s diagnostic ID or server URL and have them show up in mobile apps as that server’s push notifications.
CVE-2024-39361 1 Mattermost 1 Mattermost 2024-11-21 N/A 3.1 LOW
Mattermost versions 9.8.0, 9.7.x <= 9.7.4, 9.6.x <= 9.6.2 and 9.5.x <= 9.5.5 fail to prevent users from specifying a RemoteId for their posts which allows an attacker to specify both a remoteId and the post ID, resulting in creating a post with a user-defined post ID. This can cause some broken functionality in the channel or thread with user-defined posts
CVE-2024-39353 1 Mattermost 1 Mattermost 2024-11-21 N/A 2.7 LOW
Mattermost versions 9.5.x <= 9.5.5 and 9.8.0 fail to sanitize the RemoteClusterFrame payloads before audit logging them which allows a high privileged attacker with access to the audit logs to read message contents.
CVE-2024-37182 1 Mattermost 1 Mattermost Desktop 2024-11-21 N/A 4.7 MEDIUM
Mattermost Desktop App versions <=5.7.0 fail to correctly prompt for permission when opening external URLs which allows a remote attacker to force a victim over the Internet to run arbitrary programs on the victim's system via custom URI schemes.
