|---|---|---|---|---|
| CVE-2025-9076 | 1 Mattermost | 2 Mattermost, Mattermost Server | 2025-09-20 | 6.5 Medium |
| Mattermost versions 10.10.x <= 10.10.1 fail to properly sanitize user data during shared channel membership synchronization, which allows malicious or compromised remote clusters to access sensitive user information via unsanitized user objects.
