| 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 restrict the input in POST /api/v4/users which allows a user to manipulate the creation date in POST /api/v4/users tricking the admin into believing their account is much older. | |||||

| CVE-2024-42000 | 1 Mattermost | 1 Mattermost Server | 2026-06-17 | N/A | 2.7 LOW |
| Mattermost versions 9.10.x <= 9.10.2, 9.11.x <= 9.11.1, 9.5.x <= 9.5.9 and 10.0.x <= 10.0.0 fail to properly authorize the requests to /api/v4/channels which allows a User or System Manager, with "Read Groups" permission but with no access for channels to retrieve details about private channels that they were not a member of by sending a request to /api/v4/channels. | |||||
| CVE-2024-41926 | 1 Mattermost | 1 Mattermost Server | 2026-06-17 | N/A | 2.7 LOW |
| 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. | |||||
| CVE-2024-41162 | 1 Mattermost | 1 Mattermost Server | 2026-06-17 | N/A | 4.1 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-2024-41144 | 1 Mattermost | 1 Mattermost Server | 2026-06-17 | N/A | 5.5 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 properly validate synced posts, when shared channels are enabled, which allows a malicious remote to create/update/delete arbitrary posts in arbitrary channels | |||||
| CVE-2024-40886 | 1 Mattermost | 1 Mattermost | 2026-06-17 | N/A | 4.6 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 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 User Management page of the system console. | |||||
| CVE-2024-40884 | 1 Mattermost | 1 Mattermost Server | 2026-06-17 | 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-2024-3872 | 1 Mattermost | 1 Mattermost Mobile | 2026-06-17 | N/A | 3.1 LOW |
| Mattermost Mobile app versions 2.13.0 and earlier use a regular expression with polynomial complexity to parse certain deeplinks, which allows an unauthenticated remote attacker to freeze or crash the app via a long maliciously crafted link. | |||||
| CVE-2024-39839 | 1 Mattermost | 1 Mattermost Server | 2026-06-17 | 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-2024-39837 | 1 Mattermost | 1 Mattermost Server | 2026-06-17 | N/A | 3.8 LOW |
| 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-2024-39836 | 1 Mattermost | 1 Mattermost | 2026-06-17 | N/A | 4.8 MEDIUM |
| Mattermost versions 9.9.x <= 9.9.1, 9.5.x <= 9.5.7, 9.10.x <= 9.10.0 and 9.8.x <= 9.8.2 fail to ensure that remote/synthetic users cannot create sessions or reset passwords, which allows the munged email addresses, created by shared channels, to be used to receive email notifications and to reset passwords, when they are valid, functional emails. | |||||
| CVE-2024-39832 | 1 Mattermost | 1 Mattermost | 2026-06-17 | N/A | 6.8 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 properly safeguard an error handling which allows a malicious remote to permanently delete local data by abusing dangerous error handling, when share channels were enabled. | |||||
| CVE-2024-39830 | 1 Mattermost | 1 Mattermost | 2026-06-17 | N/A | 8.1 HIGH |
| Mattermost versions 9.8.x <= 9.8.0, 9.7.x <= 9.7.4, 9.6.x <= 9.6.2 and 9.5.x <= 9.5.5, when shared channels are enabled, fail to use constant time comparison for remote cluster tokens which allows an attacker to retrieve the remote cluster token via a timing attack during remote cluster token comparison. | |||||
| CVE-2024-39810 | 1 Mattermost | 1 Mattermost | 2026-06-17 | N/A | 4.9 MEDIUM |
| Mattermost versions 9.5.x <= 9.5.7 and 9.10.x <= 9.10.0 fail to time limit and size limit the CA path file in the ElasticSearch configuration which allows a System Role with access to the Elasticsearch system console to add any file as a CA path field, such as /dev/zero and, after testing the connection, cause the application to crash. | |||||
| CVE-2024-39807 | 1 Mattermost | 1 Mattermost | 2026-06-17 | N/A | 3.1 LOW |
| Mattermost versions 9.5.x <= 9.5.5 and 9.8.0 fail to properly sanitize the recipients of a webhook event which allows an attacker monitoring webhook events to retrieve the channel IDs of archived or restored channels. | |||||
| CVE-2024-39777 | 1 Mattermost | 1 Mattermost | 2026-06-17 | N/A | 8.7 HIGH |
| 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 unsolicited invites to expose access to local channels, when shared channels are enabled, which allows a malicious remote to send an invite with the ID of an existing local channel, and that local channel will then become shared without the consent of the local admin. | |||||
| CVE-2024-39772 | 1 Mattermost | 1 Mattermost Desktop | 2026-06-17 | N/A | 3.7 LOW |
| Mattermost Desktop App versions <=5.8.0 fail to safeguard screen capture functionality which allows an attacker to silently capture high-quality screenshots via JavaScript APIs. | |||||
| CVE-2024-39767 | 1 Mattermost | 1 Mattermost Mobile | 2026-06-17 | N/A | 4.2 MEDIUM |
| Mattermost Mobile Apps versions <=2.16.0 fail to validate that the push notifications received for a server actually came from this serve that which allows a malicious server to send push notifications with another server’s diagnostic ID or server URL and have them show up in mobile apps as that server’s push notifications. | |||||
| CVE-2024-39613 | 1 Mattermost | 1 Mattermost Desktop | 2026-06-17 | N/A | 5.3 MEDIUM |
| Mattermost Desktop App versions <=5.8.0 fail to specify an absolute path when searching the cmd.exe file, which allows a local attacker who is able to put an cmd.exe file in the Downloads folder of a user's machine to cause remote code execution on that machine. | |||||
