CVE-2024-52032 1 Mattermost 1 Mattermost Server 2024-11-14 N/A 4.3 MEDIUM
Mattermost versions 10.0.x <= 10.0.0 and 9.11.x <= 9.11.2 fail to properly query ElasticSearch when searching for the channel name in channel switcher which allows an attacker to get private channels names of channels that they are not a member of, when Elasticsearch v8 was enabled.
CVE-2024-46872 1 Mattermost 1 Mattermost Server 2024-11-08 N/A 4.6 MEDIUM
Mattermost versions 9.10.x <= 9.10.2, 9.11.x <= 9.11.1, 9.5.x <= 9.5.9 fail to sanitize user inputs in the frontend that are used for redirection which allows for a one-click client-side path traversal that is leading to CSRF in Playbooks
CVE-2024-40884 1 Mattermost 1 Mattermost Server 2024-10-17 N/A 2.7 LOW
Mattermost versions 9.5.x <= 9.5.7, 9.10.x <= 9.10.0 fail to properly enforce permissions which allows a team admin user without "Add Team Members" permission to disable the invite URL.
CVE-2024-43780 1 Mattermost 1 Mattermost Server 2024-10-16 N/A 4.3 MEDIUM
Mattermost versions 9.9.x <= 9.9.1, 9.5.x <= 9.5.7, 9.10.0, 9.8.x <= 9.8.2 fail to enforce permissions which allows a guest user with read access to upload files to a channel.
CVE-2024-42497 1 Mattermost 1 Mattermost Server 2024-10-16 N/A 4.9 MEDIUM
Mattermost versions 9.9.x <= 9.9.1, 9.5.x <= 9.5.7, 9.10.x <= 9.10.0, 9.8.x <= 9.8.2 fail to properly enforce permissions which allows a user with systems manager role with read-only access to teams to perform write operations on teams.
CVE-2024-42406 1 Mattermost 1 Mattermost Server 2024-10-01 N/A 5.4 MEDIUM
Mattermost versions 9.11.x <= 9.11.0, 9.10.x <= 9.10.1, 9.9.x <= 9.9.2 and 9.5.x <= 9.5.8 fail to properly authorize requests when viewing archived channels is disabled, which allows an attacker to retrieve post and file information about archived channels. Examples are flagged or unread posts as well as files.
CVE-2024-47145 1 Mattermost 1 Mattermost Server 2024-09-26 N/A 4.3 MEDIUM
Mattermost versions 9.5.x <= 9.5.8 fail to properly authorize access to archived channels when viewing archived channels is disabled, which allows an attacker to view posts and files of archived channels via file links.
CVE-2024-47003 1 Mattermost 1 Mattermost Server 2024-09-26 N/A 6.5 MEDIUM
Mattermost versions 9.11.x <= 9.11.0 and 9.5.x <= 9.5.8 fail to validate that the message of the permalink post is a string, which allows an attacker to send a non-string value as the message of a permalink post and crash the frontend.
CVE-2024-45843 1 Mattermost 1 Mattermost Server 2024-09-26 N/A 5.4 MEDIUM
Mattermost versions 9.5.x <= 9.5.8 fail to include the metadata endpoints of Oracle Cloud and Alibaba in the SSRF denylist, which allows an attacker to possibly cause an SSRF if Mattermost was deployed in Oracle Cloud or Alibaba.
CVE-2024-39837 1 Mattermost 1 Mattermost Server 2024-09-04 N/A 5.4 MEDIUM
Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6 fail to properly restrict channel creation which allows a malicious remote to create arbitrary channels, when shared channels were enabled.
CVE-2024-39839 1 Mattermost 1 Mattermost Server 2024-09-04 N/A 4.3 MEDIUM
Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5, 9.8.x <= 9.8.1 fail to disallow users to set their own remote username, when shared channels were enabled, which allows a user on a remote to set their remote username prop to an arbitrary string, which would be then synced to the local server as long as the user hadn't been synced before.
CVE-2024-41144 1 Mattermost 1 Mattermost Server 2024-09-04 N/A 7.1 HIGH
Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5, 9.8.x <= 9.8.1 fail to properly validate synced posts, when shared channels are enabled,  which allows a malicious remote to create/update/delete arbitrary posts in arbitrary channels
CVE-2024-41162 1 Mattermost 1 Mattermost Server 2024-09-04 N/A 4.3 MEDIUM
Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5 and 9.8.x <= 9.8.1 fail to disallow the modification of local channels by a remote, when shared channels are enabled, which allows a malicious remote to make an arbitrary local channel read-only.
CVE-2024-41926 1 Mattermost 1 Mattermost Server 2024-09-04 N/A 4.3 MEDIUM
Mattermost versions 9.9.x <= 9.9.0 and 9.5.x <= 9.5.6 fail to validate the source of sync messages and only allow the correct remote IDs, which allows a malicious remote to set arbitrary RemoteId values for synced users and therefore claim that a user was synced from another remote.
