CVE-2024-39361
Last modified
CVE-2024-39361 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. Mattermost versions 9.8.0, 9.7.x <= 9.7.4, 9.6.x <= 9.6.2 and 9.5.x <= 9.5.5 fail to prevent users from specifying a RemoteId for their posts which allows an attacker to specify both a remoteId and the post ID, resulting in creating a post with a user-defined post ID. This can cause some broken functionality in the channel or thread with user-defined posts. EPSS estimates a 0.28% chance of exploitation in the next 30 days.
