| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-08-01 | CVE-2024-29977 | Unspecified vulnerability in Mattermost Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6 fail to properly validate synced reactions, when shared channels are enabled, which allows a malicious remote to create arbitrary reactions on arbitrary posts | 4.3 |
| 2024-08-01 | CVE-2024-36492 | Unspecified vulnerability in Mattermost Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5, 9.8.x <= 9.8.1 fail to disallow the modification of local users when syncing users in shared channels. | 6.4 |
| 2024-08-01 | CVE-2024-39274 | Unspecified vulnerability in Mattermost 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 properly validate that the channel that comes from the sync message is a shared channel, when shared channels are enabled, which allows a malicious remote to add users to arbitrary teams and channels | 6.5 |
| 2024-08-01 | CVE-2024-39837 | Unspecified vulnerability in Mattermost Server Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6 fail to properly restrict channel creation which allows a malicious remote to create arbitrary channels, when shared channels were enabled. | 5.4 |
| 2024-08-01 | CVE-2024-39839 | 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, 9.8.x <= 9.8.1 fail to disallow users to set their own remote username, when shared channels were enabled, which allows a user on a remote to set their remote username prop to an arbitrary string, which would be then synced to the local server as long as the user hadn't been synced before. | 4.3 |
| 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. | 4.3 |
| 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. | 4.3 |
| 2024-07-15 | CVE-2024-32945 | Missing Initialization of Resource vulnerability in Mattermost Mobile 1.26.0/1.29.0/1.30.0 Mattermost Mobile Apps versions <=2.16.0 fail to protect against abuse of a globally shared MathJax state which allows an attacker to change the contents of a LateX post, by creating another post with specific macro definitions. | 5.3 |
| 2024-07-15 | CVE-2024-39767 | Improper Authentication vulnerability in Mattermost Mobile 1.26.0/1.29.0/1.30.0 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. | 6.5 |
| 2024-07-03 | CVE-2024-36257 | Unspecified vulnerability in Mattermost Mattermost versions 9.5.x <= 9.5.5 and 9.8.0, when using shared channels with multiple remote servers connected, fail to check that the remote server A requesting the server B to update the profile picture of a user is the remote that actually has the user as a local one . This allows a malicious remote A to change the profile images of users that belong to another remote server C that is connected to the server A. | 5.3 |
