CVSS 3.1
6.5 mediumCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2024-24988
Medium (6.5) in mattermost mattermost server. EPSS 0.7% chance of exploitation in the next 30 days. Fixed in github.com/mattermost/mattermost/server/v8 9.2.5, 9.3.1.
Mattermost fails to properly validate the length of the emoji value in the custom user status, allowing an attacker to send multiple times a very long string as an emoji value causing high resource consumption and possibly crashing the server.
