| CVE-2025-24972 | 1 Discourse | 1 Discourse | 2026-06-17 | N/A | 4.3 MEDIUM |
| Discourse is an open-source discussion platform. Prior to versions `3.3.4` on the `stable` branch and `3.4.0.beta5` on the `beta` branch, in specific circumstances, users could be added to group direct messages despite disabling direct messaging in their preferences. Versions `3.3.4` and `3.4.0.beta5` contain a patch for the issue. A workaround is available. If a user disables chat in their preferences then they cannot be added to new group chats. | |||||
| CVE-2025-24808 | 1 Discourse | 1 Discourse | 2026-06-17 | N/A | 4.3 MEDIUM |
| Discourse is an open-source discussion platform. Prior to versions `3.3.4` on the `stable` branch and `3.4.0.beta5` on the `beta` branch, someone who is about to reach the limit of users in a group DM may send requests to add new users in parallel. The requests might all go through ignoring the limit due to a race condition. The patch in versions `3.3.4` and `3.4.0.beta5` uses the `lock` step in service to wrap part of the `add_users_to_channel` service inside a distributed lock/mutex in order to avoid the race condition. | |||||
