|---|---|---|---|---|
| CVE-2025-4128 | 1 Mattermost | 1 Mattermost Server | 2025-07-08 | 3.1 Low |
| Mattermost versions 10.5.x <= 10.5.4, 9.11.x <= 9.11.13 fail to properly restrict API access to team information, allowing guest users to bypass permissions and view information about public teams they are not members of via a direct API call to /api/v4/teams/{team_id}. | ||||
| CVE-2024-29215 | 1 Mattermost | 1 Mattermost Server | 2025-07-08 | 4.3 Medium |
| Mattermost versions 9.5.x <= 9.5.3, 9.7.x <= 9.7.1, 9.6.x <= 9.6.1, 8.1.x <= 8.1.12 fail to enforce proper access control which allows a user to run a slash command in a channel they are not a member of via linking a playbook run to that channel and running a slash command as a playbook task command. | ||||
| CVE-2025-4981 | 1 Mattermost | 1 Mattermost Server | 2025-07-08 | 9.9 Critical |
| Mattermost versions 10.5.x <= 10.5.5, 9.11.x <= 9.11.15, 10.8.x <= 10.8.0, 10.7.x <= 10.7.2, 10.6.x <= 10.6.5 fail to sanitize filenames in the archive extractor which allows authenticated users to write files to arbitrary locations on the filesystem via uploading archives with path traversal sequences in filenames, potentially leading to remote code execution. The vulnerability impacts instances where file uploads and document search by content is enabled (FileSettings.EnableFileAttachments = true and FileSettings.ExtractContent = true). These configuration settings are enabled by default. | ||||
| CVE-2025-4573 | 1 Mattermost | 1 Mattermost Server | 2025-07-08 | 4.1 Medium |
| Mattermost versions 10.7.x <= 10.7.1, 10.6.x <= 10.6.3, 10.5.x <= 10.5.4, 9.11.x <= 9.11.13 fail to properly validate LDAP group ID attributes, allowing an authenticated administrator with PermissionSysconsoleWriteUserManagementGroups permission to execute LDAP search filter injection via the PUT /api/v4/ldap/groups/{remote_id}/link API when objectGUID is configured as the Group ID Attribute. | ||||
| CVE-2025-3611 | 1 Mattermost | 1 Mattermost Server | 2025-07-08 | 3.1 Low |
| Mattermost versions 10.7.x <= 10.7.0, 10.5.x <= 10.5.3, 9.11.x <= 9.11.12 fails to properly enforce access control restrictions for System Manager roles, allowing authenticated users with System Manager privileges to view team details they should not have access to via direct API requests to team endpoints, even when explicitly configured with 'No access' to Teams in the System Console. | ||||
| CVE-2025-3227 | 1 Mattermost | 1 Mattermost Server | 2025-07-08 | 4.3 Medium |
| Mattermost versions 10.5.x <= 10.5.5, 9.11.x <= 9.11.15, 10.8.x <= 10.8.0, 10.7.x <= 10.7.2, 10.6.x <= 10.6.5 fail to properly enforce channel member management permissions in playbook runs, allowing authenticated users without the 'Manage Channel Members' permission to add or remove users from public and private channels by manipulating playbook run participants when the run is linked to a channel. | ||||
| CVE-2025-3228 | 1 Mattermost | 1 Mattermost Server | 2025-07-08 | 4.3 Medium |
| Mattermost versions 10.5.x <= 10.5.5, 9.11.x <= 9.11.15, 10.8.x <= 10.8.0, 10.7.x <= 10.7.2, 10.6.x <= 10.6.5 fail to properly retrieve requestorInfo from playbooks handler for guest users which allows an attacker access to the playbook run. | ||||
| CVE-2025-46702 | 1 Mattermost | 1 Mattermost Server | 2025-07-08 | 5.4 Medium |
| Mattermost versions 10.5.x <= 10.5.5, 9.11.x <= 9.11.15, 10.8.x <= 10.8.0, 10.7.x <= 10.7.2, 10.6.x <= 10.6.5 fail to properly enforce channel member management permissions when adding participants to playbook runs. This allows authenticated users with member-level permissions to bypass system admin restrictions and add or remove users to/from private channels via the playbook run participants feature, even when the 'Manage Members' permission has been explicitly removed. This can lead to unauthorized access to sensitive channel content and allow guest users to gain channel management privileges. | ||||
| CVE-2025-47871 | 1 Mattermost | 1 Mattermost Server | 2025-07-08 | 4.3 Medium |
| Mattermost versions 10.5.x <= 10.5.5, 9.11.x <= 9.11.15, 10.8.x <= 10.8.0, 10.7.x <= 10.7.2, 10.6.x <= 10.6.5 fail to properly validate channel membership when retrieving playbook run metadata, allowing authenticated users who are playbook members but not channel members to access sensitive information about linked private channels including channel name, display name, and participant count through the run metadata API endpoint. | ||||
| CVE-2023-47858 | 1 Mattermost | 1 Mattermost Server | 2025-06-17 | 4.3 Medium |
| Mattermost fails to properly verify the permissions needed for viewing archived public channels, allowing a member of one team to get details about the archived public channels of another team via the GET /api/v4/teams/<team-id>/channels/deleted endpoint. | ||||
| CVE-2023-50333 | 1 Mattermost | 1 Mattermost Server | 2025-06-17 | 3.7 Low |
| Mattermost fails to update the permissions of the current session for a user who was just demoted to guest, allowing freshly demoted guests to change group names. | ||||
| CVE-2023-48732 | 1 Mattermost | 1 Mattermost Server | 2025-06-03 | 4.3 Medium |
| Mattermost fails to scope the WebSocket response around notified users to a each user separately resulting in the WebSocket broadcasting the information about who was notified about a post to everyone else in the channel. | ||||
| CVE-2023-45316 | 1 Mattermost | 1 Mattermost Server | 2025-05-24 | 7.3 High |
| Mattermost fails to validate if a relative path is passed in /plugins/playbooks/api/v0/telemetry/run/<telem_run_id> as a telemetry run ID, allowing an attacker to use a path traversal payload that points to a different endpoint leading to a CSRF attack. | ||||
| CVE-2023-6727 | 1 Mattermost | 1 Mattermost Server | 2025-05-24 | 3.1 Low |
| Mattermost fails to perform correct authorization checks when creating a playbook action, allowing users without access to the playbook to create playbook actions. If the playbook action created is to post a message in a channel based on specific keywords in a post, some playbook information, like the name, can be leaked. | ||||
| CVE-2023-6547 | 1 Mattermost | 1 Mattermost Server | 2025-05-12 | 3.7 Low |
| Mattermost fails to validate team membership when a user attempts to access a playbook, allowing a user with permissions to a playbook but no permissions to the team the playbook is on to access and modify the playbook. This can happen if the user was once a member of the team, got permissions to the playbook and was then removed from the team. | ||||
| CVE-2024-4198 | 1 Mattermost | 1 Mattermost Server | 2025-05-12 | 2.7 Low |
| Mattermost versions 9.6.0, 9.5.x before 9.5.3, and 8.1.x before 8.1.12 fail to fully validate role changes which allows an attacker authenticated as team admin to demote users to guest via crafted HTTP requests. | ||||
| CVE-2024-4195 | 1 Mattermost | 1 Mattermost Server | 2025-05-12 | 2.7 Low |
| Mattermost versions 9.6.0, 9.5.x before 9.5.3, and 8.1.x before 8.1.12 fail to fully validate role changes, which allows an attacker authenticated as a team admin to promote guests to team admins via crafted HTTP requests. | ||||
| CVE-2024-4183 | 1 Mattermost | 1 Mattermost Server | 2025-05-12 | 4.3 Medium |
| Mattermost versions 8.1.x before 8.1.12, 9.6.x before 9.6.1, 9.5.x before 9.5.3, 9.4.x before 9.4.5 fail to limit the number of active sessions, which allows an authenticated attacker to crash the server via repeated requests to the getSessions API after flooding the sessions table. | ||||
| CVE-2024-4182 | 1 Mattermost | 1 Mattermost Server | 2025-05-12 | 4.3 Medium |
| Mattermost versions 9.6.0, 9.5.x before 9.5.3, 9.4.x before 9.4.5, and 8.1.x before 8.1.12 fail to handle JSON parsing errors in custom status values, which allows an authenticated attacker to crash other users' web clients via a malformed custom status. | ||||
| CVE-2024-32046 | 1 Mattermost | 1 Mattermost Server | 2025-05-12 | 4.3 Medium |
| Mattermost versions 9.6.x <= 9.6.0, 9.5.x <= 9.5.2, 9.4.x <= 9.4.4 and 8.1.x <= 8.1.11 fail to remove detailed error messages in API requests even if the developer mode is off which allows an attacker to get information about the server such as the full path were files are stored | ||||
