| CVE-2025-2527 | 1 Mattermost | 2 Mattermost, Mattermost Server | 2025-08-22 | 4.3 Medium |
| Mattermost versions 10.5.x <= 10.5.2, 9.11.x <= 9.11.11 failed to properly verify a user's permissions when accessing groups, which allows an attacker to view group information via an API request. | ||||
| CVE-2025-49222 | 1 Mattermost | 1 Mattermost | 2025-08-22 | 6.8 Medium |
| Mattermost versions 10.8.x <= 10.8.3, 10.5.x <= 10.5.8, 9.11.x <= 9.11.17, 10.9.x <= 10.9.2, 10.10.x <= 10.10.0 fail to validate upload types in remote cluster upload sessions which allows a system admin to upload non-attachment file types via shared channels that could potentially be placed in arbitrary filesystem directories. | ||||
| CVE-2025-36530 | 1 Mattermost | 1 Mattermost | 2025-08-22 | 6.8 Medium |
| Mattermost versions 10.9.x <= 10.9.1, 10.8.x <= 10.8.3, 10.5.x <= 10.5.8, 9.11.x <= 9.11.17 fail to properly validate file paths during plugin import operations which allows restricted admin users to install unauthorized custom plugins via path traversal in the import functionality, bypassing plugin signature enforcement and marketplace restrictions. | ||||
| CVE-2025-47870 | 1 Mattermost | 1 Mattermost | 2025-08-22 | 4.3 Medium |
| Mattermost versions 10.8.x <= 10.8.3, 10.5.x <= 10.5.8, 9.11.x <= 9.11.17, 10.9.x <= 10.9.2 fail to sanitize the team invite ID in the POST /api/v4/teams/:teamId/restore endpoint which allows an team admin with no member invite privileges to get the team’s invite id. | ||||
