| CVE-2023-41043 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 6.5 MEDIUM |
| Discourse is an open-source discussion platform. Prior to version 3.1.1 of the `stable` branch and version 3.2.0.beta1 of the `beta` and `tests-passed` branches, a malicious admin could create extremely large icons sprites, which would then be cached in each server process. This may cause server processes to be killed and lead to downtime. The issue is patched in version 3.1.1 of the `stable` branch and version 3.2.0.beta1 of the `beta` and `tests-passed` branches. This is only a concern for multisite installations. No action is required when the admins are trusted. | |||||
| CVE-2023-44391 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 5.3 MEDIUM |

| CVE-2023-36818 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 7.5 HIGH |
| Discourse is an open source discussion platform. In affected versions a request to create or update custom sidebar section can cause a denial of service.

| CVE-2023-43814 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 3.7 LOW |
| Discourse is an open source platform for community discussion. Attackers with details specific to a poll in a topic can use the `/polls/grouped_poll_results` endpoint to view the content of options in the poll and the number of votes for groups of poll participants. This impacts private polls where the results were intended to only be viewable by authorized users. This issue is patched in the 3.1.1 stable and 3.2.0.beta2 versions of Discourse. There is no workaround for this issue apart from upgrading to the fixed version. | |||||
| CVE-2023-43657 | 1 Discourse | 1 Discourse-encrypt | 2023-12-10 | N/A | 6.1 MEDIUM |
| discourse-encrypt is a plugin that provides a secure communication channel through Discourse. Improper escaping of encrypted topic titles could lead to a cross site scripting (XSS) issue when a site has content security policy (CSP) headers disabled. Having CSP disabled is a non-default configuration, and having it disabled with discourse-encrypt installed will result in a warning in the Discourse admin dashboard. This has been fixed in commit `9c75810af9` which is included in the latest version of the discourse-encrypt plugin. Users are advised to upgrade. Users unable to upgrade should ensure that CSP headers are enabled and properly configured. | |||||
| CVE-2023-44388 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 7.5 HIGH |
| Discourse is an open source platform for community discussion. A malicious request can cause production log files to quickly fill up and thus result in the server running out of disk space. This problem has been patched in the 3.1.1 stable and 3.2.0.beta2 versions of Discourse. It is possible to temporarily work around this problem by reducing the `client_max_body_size nginx directive`. `client_max_body_size` will limit the size of uploads that can be uploaded directly to the server. | |||||

| CVE-2023-36473 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 6.1 MEDIUM |
| Discourse is an open source discussion platform. A CSP (Content Security Policy) nonce reuse vulnerability could allow XSS attacks to bypass CSP protection.

The vulnerability is patched in the latest tests-passed, beta and stable branches. | |||||
| CVE-2023-37467 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 5.4 MEDIUM |

Prior to version 3.1.0.beta7 of the `beta` and `tests-passed` branches, a CSP (Content Security Policy) nonce reuse vulnerability was discovered could allow cross-site scripting (XSS) attacks to bypass CSP protection for anonymous (i.e. unauthenticated) users. There are no known XSS vectors at the moment, but should one be discovered, this vulnerability would allow the XSS attack to bypass CSP and execute successfully. This vulnerability isn't applicable to logged-in users. Version 3.1.0.beta7 contains a patch. The stable branch doesn't have this vulnerability. A workaround to prevent the vulnerability is to disable Google Tag Manager, i.e., unset the `gtm container id` setting. | |||||

| CVE-2023-30538 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 5.4 MEDIUM |
| Discourse is an open source platform for community discussion.

This issue is patched in the latest stable and tests-passed versions of Discourse. Users are advised to upgrade. For users unable to upgrade there are two possible workarounds: enable CDN handing of uploads (and ensure the CDN sanitizes SVG files) or disable SVG file uploads by ensuring that the `authorized extensions` site setting does not include `svg` (or reset that setting to the default, by default Discourse doesn't enable SVG uploads by users). | |||||
| CVE-2023-30606 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 4.9 MEDIUM |
| Discourse is an open source platform for community discussion. In affected versions a user logged as an administrator can call arbitrary methods on the `SiteSetting` class, notably `#clear_cache!` and `#notify_changed!`, which when done on a multisite instance, can affect the entire cluster resulting in a denial of service. Users not running in multisite environments are not affected. 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-2023-32301 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 5.3 MEDIUM |
| Discourse is an open source discussion platform.

This issue is patched in version 3.0.4 of the `stable` branch and version 3.1.0.beta5 of the `beta` and `tests-passed` branches. As a workaround, disable topic embedding if it has been enabled. | |||||
| CVE-2023-31142 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 5.3 MEDIUM |
| Discourse is an open source discussion platform. Prior to version 3.0.4 of the `stable` branch and version 3.1.0.beta5 of the `beta` and `tests-passed` branches, if a site has modified their general category permissions, they could be set back to the default. This issue is patched in version 3.0.4 of the `stable` branch and version 3.1.0.beta5 of the `beta` and `tests-passed` branches. A workaround, only if you are modifying the general category permissions, is to use a new category for the same purpose. | |||||
| CVE-2023-29196 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 6.1 MEDIUM |
| Discourse is an open source platform for community discussion. This vulnerability is not exploitable on the default install of Discourse. A custom feature must be enabled for it to work at all, and the attacker’s payload must pass the CSP to be executed. However, if an attacker succeeds in embedding Javascript that does pass the CSP, it could result in session hijacking for any users that view the attacker’s post. The vulnerability is patched in the latest tests-passed, beta and stable branches. Users are advised to upgrade. Users unable to upgrade should enable and/or restore your site's CSP to the default one provided with Discourse. Remove any embed-able hosts configured. | |||||
| CVE-2023-28440 | 1 Discourse | 1 Discourse | 2023-12-10 | N/A | 2.7 LOW |
| Discourse is an open source platform for community discussion. In affected versions a maliciously crafted request from a Discourse administrator can lead to a long-running request and eventual timeout. This has the greatest potential impact in shared hosting environments where admins are untrusted. This issue has been addressed in versions 3.0.3 and 3.1.0.beta4. Users are advised to upgrade. There are no known workarounds for this vulnerability. | |||||
