| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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-2024-41144 | 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 properly validate synced posts, when shared channels are enabled, which allows a malicious remote to create/update/delete arbitrary posts in arbitrary channels | 7.1 |
| 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 |
