| CVE-2025-24808 | 1 Discourse | 1 Discourse | 2025-08-26 | 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. | |||||
| CVE-2025-49845 | 1 Discourse | 1 Discourse | 2025-08-25 | N/A | 7.5 HIGH |
| Discourse is an open-source discussion platform. The visibility of posts typed `whisper` is controlled via the `whispers_allowed_groups` site setting. Only users that belong to groups specified in the site setting are allowed to view posts typed `whisper`. However, it has been discovered that users of versions prior to 3.4.6 on the `stable` branch and prior to 3.5.0.beta8-dev on the `tests-passed` branch can continue to see their own whispers even after losing visibility of posts typed `whisper`. This issue is patched in versions 3.4.6 and 3.5.0.beta8-dev. No known workarounds are available. | |||||
| CVE-2025-48062 | 1 Discourse | 1 Discourse | 2025-08-25 | N/A | 7.1 HIGH |
| Discourse is an open-source discussion platform. Prior to version 3.4.4 of the `stable` branch, version 3.5.0.beta5 of the `beta` branch, and version 3.5.0.beta6-dev of the `tests-passed` branch, certain invites via email may result in HTML injection in the email body if the topic title includes HTML. This includes inviting someone (without an account) to a PM and inviting someone (without an account) to a topic with a custom message. This issue is patched in version 3.4.4 of the `stable` branch, version 3.5.0.beta5 of the `beta` branch, and version 3.5.0.beta6-dev of the `tests-passed` branch. This can be worked around if the relevant templates are overridden without `{topic_title}`. | |||||
| CVE-2025-48954 | 1 Discourse | 1 Discourse | 2025-08-25 | N/A | 8.1 HIGH |
| Discourse is an open-source discussion platform. Versions prior to 3.5.0.beta6 are vulnerable to cross-site scripting when the content security policy isn't enabled when using social logins. Version 3.5.0.beta6 patches the issue. As a workaround, have the content security policy enabled. | |||||
| CVE-2025-32376 | 1 Discourse | 1 Discourse | 2025-05-16 | N/A | 4.3 MEDIUM |
| Discourse is an open-source discussion platform. Prior to versions 3.4.3 on the stable branch and 3.5.0.beta3 on the beta branch, the users limit for a DM can be bypassed, thus giving the ability to potentially create a DM with every user from a site in it. This issue has been patched in stable version 3.4.3 and beta version 3.5.0.beta3. | |||||
| CVE-2024-24748 | 1 Discourse | 1 Discourse | 2025-04-09 | N/A | 5.3 MEDIUM |
| Discourse is an open source platform for community discussion. In affected versions an attacker can learn that a secret subcategory exists under a public category which has no public subcategories. The issue is patched in the latest stable, beta and tests-passed version of Discourse. Users are advised to upgrade. There are no known workarounds for this vulnerability. | |||||
| CVE-2023-46241 | 1 Discourse | 1 Microsoft Authentication | 2025-02-05 | N/A | 9.0 CRITICAL |
| `discourse-microsoft-auth` is a plugin that enables authentication via Microsoft. On sites with the `discourse-microsoft-auth` plugin enabled, an attack can potentially take control of a victim's Discourse account. Sites that have configured their application's account type to any options other than `Accounts in this organizational directory only (O365 only - Single tenant)` are vulnerable. This vulnerability has been patched in commit c40665f44509724b64938c85def9fb2e79f62ec8 of `discourse-microsoft-auth`. A `microsoft_auth:revoke` rake task has also been added which will deactivate and log out all users that have connected their accounts to Microsoft. User API keys as well as API keys created by those users will also be revoked. The rake task will also remove the connection records to Microsoft for those users. This will allow affected users to re-verify their account emails as well as reconnect their Discourse account to Microsoft for authentication. As a workaround, disable the `discourse-microsoft-auth` plugin by setting the `microsoft_auth_enabled` site setting to `false`. Run the `microsoft_auth:log_out_users` rake task to log out all users with associated Microsoft accounts. | |||||
| CVE-2024-26145 | 1 Discourse | 1 Calendar | 2025-02-05 | N/A | 6.5 MEDIUM |
| Discourse Calendar adds the ability to create a dynamic calendar in the first post of a topic on Discourse. Uninvited users are able to gain access to private events by crafting a request to update their attendance. This problem is resolved in commit dfc4fa15f340189f177a1d1ab2cc94ffed3c1190. As a workaround, one may use post visibility to limit access. | |||||
| CVE-2024-23654 | 1 Discourse | 1 Ai | 2025-02-05 | N/A | 4.1 MEDIUM |
| discourse-ai is the AI plugin for the open-source discussion platform Discourse. Prior to commit 94ba0dadc2cf38e8f81c3936974c167219878edd, interactions with different AI services are vulnerable to admin-initiated SSRF attacks. Versions of the plugin that include commit 94ba0dadc2cf38e8f81c3936974c167219878edd contain a patch. As a workaround, one may disable the discourse-ai plugin. | |||||
| CVE-2024-24817 | 1 Discourse | 1 Calendar | 2025-02-05 | N/A | 4.3 MEDIUM |
| Discourse Calendar adds the ability to create a dynamic calendar in the first post of a topic on the open-source discussion platform Discourse. Prior to version 0.4, event invitees created in topics in private categories or PMs (private messages) can be retrieved by anyone, even if they're not logged in. This problem is resolved in version 0.4 of the discourse-calendar plugin. While no known workaround is available, putting the site behind `login_required` will disallow this endpoint to be used by anonymous users, but logged in users can still get the list of invitees in the private topics. | |||||

| Discourse-reactions is a plugin that allows user to add their reactions to the post in the Discourse messaging platform. In affected versions data about what reactions were performed on a post in a private topic could be leaked. This issue has been addressed in version 0.3. Users are advised to upgrade. Users unable to upgrade should disable the discourse-reactions plugin to fully mitigate the issue. | |||||
