| 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 | ||||
| CVE-2024-22091 | 1 Mattermost | 1 Mattermost Server | 2025-05-12 | 3.1 Low |
| Mattermost versions 8.1.x <= 8.1.10, 9.6.x <= 9.6.0, 9.5.x <= 9.5.2 and 8.1.x <= 8.1.11 fail to limit the size of a request path that includes user inputs which allows an attacker to cause excessive resource consumption, possibly leading to a DoS via sending large request paths | ||||
| CVE-2024-1888 | 1 Mattermost | 1 Mattermost Server | 2025-05-12 | 4.3 Medium |
| Mattermost fails to check the "invite_guest" permission when inviting guests of other teams to a team, allowing a member with permissions to add other members but not to add guests to add a guest to a team as long as the guest was already a guest in another team of the server | ||||
| CVE-2024-23488 | 1 Mattermost | 1 Mattermost Server | 2025-05-12 | 3.1 Low |

| CVE-2025-41395 | 1 Mattermost | 1 Mattermost | 2025-04-29 | 6.5 Medium |
| Mattermost versions 10.4.x <= 10.4.2, 10.5.x <= 10.5.0, 9.11.x <= 9.11.10 fail to properly validate the props used by the RetrospectivePost custom post type in the Playbooks plugin, which allows an attacker to create a specially crafted post with maliciously crafted props and cause a denial of service (DoS) of the web app for all users. | ||||
