| CVE-2024-47773 | 1 Discourse | 1 Discourse | 2025-08-26 | N/A | 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 | N/A | 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. The problem has been patched in version 3.2.3 on the `stable` branch and version 3.3.0.beta3 on the `tests-passed` branch. There are no known workarounds available for this vulnerability. | |||||
| CVE-2024-27100 | 1 Discourse | 1 Discourse | 2025-08-26 | N/A | 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 | N/A | 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 | N/A | 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 | N/A | 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-2024-52589 | 1 Discourse | 1 Discourse | 2025-08-26 | N/A | 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. This problem is patched in the latest version of Discourse. Users unable to upgrade should remove moderator role from untrusted users. | |||||
| CVE-2024-52794 | 1 Discourse | 1 Discourse | 2025-08-26 | N/A | 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 | N/A | 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. | |||||
| 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-2025-32376 | 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-2024-39320 | 1 Discourse | 1 Discourse | 2024-11-21 | N/A | 6.1 MEDIUM |
| Discourse is an open source discussion platform. Prior to 3.2.5 and 3.3.0.beta5, the vulnerability allows an attacker to inject iframes from any domain, bypassing the intended restrictions enforced by the allowed_iframes setting. This vulnerability is fixed in 3.2.5 and 3.3.0.beta5. | |||||
| CVE-2024-37299 | 1 Discourse | 1 Discourse | 2024-11-21 | N/A | 4.9 MEDIUM |
| Discourse is an open source discussion platform. Prior to 3.2.5 and 3.3.0.beta5, crafting requests to submit very long tag group names can reduce the availability of a Discourse instance. This vulnerability is fixed in 3.2.5 and 3.3.0.beta5. | |||||
| CVE-2024-37165 | 1 Discourse | 1 Discourse | 2024-11-21 | N/A | 6.3 MEDIUM |
| Discourse is an open source discussion platform. Prior to 3.2.3 and 3.3.0.beta3, improperly sanitized Onebox data could lead to an XSS vulnerability in some situations.

| CVE-2024-37157 | 1 Discourse | 1 Discourse | 2024-11-21 | N/A | 6.4 MEDIUM |
| Discourse is an open-source discussion platform. Prior to version 3.2.3 on the `stable` branch and version 3.3.0.beta4 on the `beta` and `tests-passed` branches, a malicious actor could get the FastImage library to redirect requests to an internal Discourse IP. This issue is patched in version 3.2.3 on the `stable` branch and version 3.3.0.beta4 on the `beta` and `tests-passed` branches. No known workarounds are available. | |||||
| CVE-2024-36122 | 1 Discourse | 1 Discourse | 2024-11-21 | N/A | 2.4 LOW |
| Discourse is an open-source discussion platform. Prior to version 3.2.3 on the `stable` branch and version 3.3.0.beta4 on the `beta` and `tests-passed` branches, moderators using the review queue to review users may see a users email address even when the Allow moderators to view email addresses setting is disabled. This issue is patched in version 3.2.3 on the `stable` branch and version 3.3.0.beta4 on the `beta` and `tests-passed` branches. As possible workarounds, either prevent moderators from accessing the review queue or disable the approve suspect users site setting and the must approve users site setting to prevent users from being added to the review queue. | |||||
| CVE-2024-36113 | 1 Discourse | 1 Discourse | 2024-11-21 | N/A | 4.9 MEDIUM |
