4.3 mediumCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:NCVE-2024-1952
Medium (4.3) in mattermost mattermost server. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in github.com/mattermost/mattermost/server/v8 9.4.0.
Mattermost version 8.1.x before 8.1.9 fails to sanitize data associated with permalinks when a plugin updates an ephemeral post, allowing an authenticated attacker who can control the ephemeral post update to access individual posts' contents in channels they are not a member of.
