CVSS 3.1
4.9 mediumCVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:NCVE-2025-8023
Medium (4.9) in mattermost mattermost server. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in github.com/mattermost/mattermost-server 10.5.9, 10.5.9+incompatible, 10.8.4.
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 fails to sanitize path traversal sequences in template file destination paths, which allows a system admin to perform path traversal attacks via malicious path components, potentially enabling malicious file placement outside intended directories.
