| CVE-2024-47773 | 1 Discourse | 1 Discourse | 2025-08-26 | 8.2 High |
| Discourse is an open source platform for community discussion. An attacker can make several XHR requests until the cache is poisoned with a response without any preloaded data. This issue only affects anonymous visitors of the site. This problem has been patched in the latest version of Discourse. Users are advised to upgrade. Users unable to upgrade should disable anonymous cache by setting the `DISCOURSE_DISABLE_ANON_CACHE` environment variable to a non-empty value. | ||||
| CVE-2024-35227 | 1 Discourse | 1 Discourse | 2025-08-26 | 7.5 High |
| Discourse is an open-source discussion platform. Prior to version 3.2.3 on the `stable` branch and version 3.3.0.beta3 on the `tests-passed` branch, Oneboxing against a carefully crafted malicious URL can reduce the availability of a Discourse instance.

| CVE-2024-27100 | 1 Discourse | 1 Discourse | 2025-08-26 | 6.5 Medium |
| Discourse is an open source platform for community discussion. In affected versions the endpoints for suspending users, silencing users and exporting CSV files weren't enforcing limits on the sizes of the parameters that they accept. This could lead to excessive resource consumption which could render an instance inoperable. A site could be disrupted by either a malicious moderator on the same site or a malicious staff member on another site in the same multisite cluster. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. Users are advised to upgrade. There are no known workarounds for this vulnerability. | ||||
| CVE-2024-27085 | 1 Discourse | 1 Discourse | 2025-08-26 | 6.5 Medium |
| Discourse is an open source platform for community discussion. In affected versions users that are allowed to invite others can inject arbitrarily large data in parameters used in the invite route. The problem has been patched in the latest version of Discourse. Users are advised to upgrade. Users unable to upgrade should disable invites or restrict access to them using the `invite allowed groups` site setting. | ||||
| CVE-2024-24827 | 1 Discourse | 1 Discourse | 2025-08-26 | 5.3 Medium |
| Discourse is an open source platform for community discussion. Without a rate limit on the POST /uploads endpoint, it makes it easier for an attacker to carry out a DoS attack on the server since creating an upload can be a resource intensive process. Do note that the impact varies from site to site as various site settings like `max_image_size_kb`, `max_attachment_size_kb` and `max_image_megapixels` will determine the amount of resources used when creating an upload. The issue is patched in the latest stable, beta and tests-passed version of Discourse. Users are advised to upgrade. Users unable to upgrade should reduce `max_image_size_kb`, `max_attachment_size_kb` and `max_image_megapixels` as smaller uploads require less resources to process. Alternatively, `client_max_body_size` can be reduced in Nginx to prevent large uploads from reaching the server. | ||||
| CVE-2025-23023 | 1 Discourse | 1 Discourse | 2025-08-26 | 8.2 High |
| Discourse is an open source platform for community discussion. In affected versions an attacker can carefully craft a request with the right request headers to poison the anonymous cache (for example, the cache may have a response with missing preloaded data). This issue only affects anonymous visitors of the site. This problem has been patched in the latest version of Discourse. Users are advised to upgrade. Users unable to upgrade may disable anonymous cache by setting the `DISCOURSE_DISABLE_ANON_CACHE` environment variable to a non-empty value. | ||||
| CVE-2024-53994 | 1 Discourse | 1 Discourse | 2025-08-26 | 4.3 Medium |
| Discourse is an open source platform for community discussion. In affected versions users who disable chat in preferences could still be reachable in some cases. This problem has been patched in the latest version of Discourse. Users are advised to upgrade. Users unable to upgrade should disable the chat plugin within site settings. | ||||
| CVE-2024-53266 | 1 Discourse | 1 Discourse | 2025-08-26 | 4.3 Medium |
| Discourse is an open source platform for community discussion. In affected versions with some combinations of plugins, and with CSP disabled, activity streams in the user's profile page may be vulnerable to XSS. This has been patched in the latest version of Discourse core. Users are advised to upgrade. Users unable to upgrade should ensure CSP is enabled. | ||||
| CVE-2024-53851 | 1 Discourse | 1 Discourse | 2025-08-26 | 4.3 Medium |
| Discourse is an open source platform for community discussion. In affected versions the endpoint for generating inline oneboxes for URLs wasn't enforcing limits on the number of URLs that it accepted, allowing a malicious user to inflict denial of service on some parts of the app. This vulnerability is only exploitable by authenticated users. This issue has been patched in the latest stable, beta and tests-passed versions of Discourse. Users are advised to upgrade. Users unable to upgrade should turn off the `enable inline onebox on all domains` site setting and remove all entries from the `allowed inline onebox domains` site setting. | ||||
| CVE-2025-22602 | 1 Discourse | 1 Discourse | 2025-08-26 | 6.5 Medium |
| Discourse is an open source platform for community discussion. In affected versions an attacker can execute arbitrary JavaScript on users' browsers by posting a malicious video placeholder html element. This issue only affects sites with CSP disabled. This problem has been patched in the latest version of Discourse. Users are advised to upgrade. Users unable to upgrade should enable CSP. | ||||
| CVE-2025-22601 | 1 Discourse | 1 Discourse | 2025-08-26 | 3.1 Low |
| Discourse is an open source platform for community discussion. In affected versions an attacker can trick a target user to make changes to their own username via carefully crafted link using the `activate-account` route. This problem has been patched in the latest version of Discourse. Users are advised to upgrade. There are no known workarounds for this vulnerability. | ||||
| CVE-2024-56328 | 1 Discourse | 1 Discourse | 2025-08-26 | 6.5 Medium |
| Discourse is an open source platform for community discussion. An attacker can execute arbitrary JavaScript on users' browsers by posting a maliciously crafted onebox url. This issue only affects sites with CSP disabled. This problem has been patched in the latest version of Discourse. Users are advised to upgrade. Users unable to upgrade should enable CSP, disable inline Oneboxes globally, or allow specific domains for Oneboxing. | ||||
| CVE-2024-49765 | 1 Discourse | 1 Discourse | 2025-08-26 | 5.3 Medium |
| Discourse is an open source platform for community discussion. Sites that are using discourse connect but still have local logins enabled could allow attackers to bypass discourse connect to create accounts and login. This problem is patched in the latest version of Discourse. Users unable to upgrade who are using discourse connect may disable all other login methods as a workaround. | ||||
| CVE-2024-52589 | 1 Discourse | 1 Discourse | 2025-08-26 | 2.2 Low |
| Discourse is an open source platform for community discussion. Moderators can see the Screened emails list in the admin dashboard, and through that can learn the email of a user.

| CVE-2024-52794 | 1 Discourse | 1 Discourse | 2025-08-26 | 6.8 Medium |
| Discourse is an open source platform for community discussion. Users clicking on the lightbox thumbnails could be affected. This problem is patched in the latest version of Discourse. Users are advised to upgrade. There are no known workarounds for this vulnerability. | ||||
| CVE-2024-53991 | 1 Discourse | 1 Discourse | 2025-08-26 | 7.5 High |
| Discourse is an open source platform for community discussion. This vulnerability only impacts Discourse instances configured to use `FileStore::LocalStore` which means uploads and backups are stored locally on disk. If an attacker knows the name of the Discourse backup file, the attacker can trick nginx into sending the Discourse backup file with a well crafted request. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. Users are advised to upgrade. Users unable to upgrade can either 1. Download all local backups on to another storage device, disable the `enable_backups` site setting and delete all backups until the site has been upgraded to pull in the fix. Or 2. Change the `backup_location` site setting to `s3` so that backups are stored and downloaded directly from S3. | ||||
