| CVE-2025-47870 | 1 Mattermost | 1 Mattermost Server | 2026-06-17 | N/A | 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. | |||||
| CVE-2025-47700 | 1 Mattermost | 1 Mattermost Server | 2026-06-17 | N/A | 3.5 LOW |
