CVE-2023-38684 | 1 Discourse | 1 Discourse | 2024-11-21 | 5.3 Medium |

CVE-2023-37467 | 1 Discourse | 1 Discourse | 2024-11-21 | 6.8 Medium |
Discourse is an open source discussion platform. 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-2023-36818 | 1 Discourse | 1 Discourse | 2024-11-21 | 6.5 Medium |

CVE-2023-36473 | 1 Discourse | 1 Discourse | 2024-11-21 | 6.8 Medium |
Discourse is an open source discussion platform. A CSP (Content Security Policy) nonce reuse vulnerability could allow XSS attacks to bypass CSP protection. There are no known XSS vectors at the moment, but should one be discovered, this vulnerability would allow the XSS attack to completely bypass CSP. The vulnerability is patched in the latest tests-passed, beta and stable branches. | ||||
CVE-2023-36466 | 1 Discourse | 1 Discourse | 2024-11-21 | 3.5 Low |
Discourse is an open source discussion platform.

CVE-2022-37458 | 1 Discourse | 1 Discourse | 2024-11-21 | 7.2 High |

CVE-2021-43840 | 1 Discourse | 1 Message Bus | 2024-11-21 | 4.4 Medium |
message_bus is a messaging bus for Ruby processes and web clients. In versions prior to 3.3.7 users who deployed message bus with diagnostics features enabled (default off) are vulnerable to a path traversal bug, which could lead to disclosure of secret information on a machine if an unintended user were to gain access to the diagnostic route. The impact is also greater if there is no proxy for your web application as the number of steps up the directories is not bounded. For deployments which uses a proxy, the impact varies. For example, If a request goes through a proxy like Nginx with `merge_slashes` enabled, the number of steps up the directories that can be read is limited to 3 levels. This issue has been patched in version 3.3.7. Users unable to upgrade should ensure that MessageBus::Diagnostics is disabled. | ||||
CVE-2021-43827 | 1 Discourse | 1 Discourse Footnote | 2024-11-21 | 4.3 Medium |
discourse-footnote is a library providing footnotes for posts in Discourse. ### Impact When posting an inline footnote wrapped in `<a>` tags (e.g. `<a>^[footnote]</a>`, the resulting rendered HTML would include a nested `<a>`, which is stripped by Nokogiri because it is not valid. This then caused a javascript error on topic pages because we were looking for an `<a>` element inside the footnote reference span and getting its ID, and because it did not exist we got a null reference error in javascript. Users are advised to update to version 0.2. As a workaround editing offending posts from the rails console or the database console for self-hosters, or disabling the plugin in the admin panel can mitigate this issue. | ||||
CVE-2021-43794 | 1 Discourse | 1 Discourse | 2024-11-21 | 5.3 Medium |
Discourse is an open source discussion platform. In affected versions an attacker can poison the cache for anonymous (i.e. not logged in) users, such that the users are shown a JSON blob instead of the HTML page. This can lead to a partial denial-of-service. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. | ||||
CVE-2021-43793 | 1 Discourse | 1 Discourse | 2024-11-21 | 4.3 Medium |

CVE-2021-43792 | 1 Discourse | 1 Discourse | 2024-11-21 | 4.3 Medium |
Discourse is an open source discussion platform. In affected versions a vulnerability affects users of tag groups who use the "Tags are visible only to the following groups" feature. A tag group may only allow a certain group (e.g. staff) to view certain tags. Users who were tracking or watching the tags via /preferences/tags, then have their staff status revoked will still see notifications related to the tag, but will not see the tag on each topic. This issue has been patched in stable version 2.7.11. Users are advised to upgrade as soon as possible. | ||||
CVE-2021-41271 | 1 Discourse | 1 Discourse | 2024-11-21 | 4.8 Medium |
Discourse is a platform for community discussion. In affected versions a maliciously crafted request could cause an error response to be cached by intermediate proxies. This could cause a loss of confidentiality for some content. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. | ||||
CVE-2021-41263 | 1 Discourse | 1 Rails Multisite | 2024-11-21 | 8.3 High |
rails_multisite provides multi-db support for Rails applications. In affected versions this vulnerability impacts any Rails applications using `rails_multisite` alongside Rails' signed/encrypted cookies. Depending on how the application makes use of these cookies, it may be possible for an attacker to re-use cookies on different 'sites' within a multi-site Rails application. The issue has been patched in v4 of the `rails_multisite` gem. Note that this upgrade will invalidate all previous signed/encrypted cookies. The impact of this invalidation will vary based on the application architecture. | ||||
CVE-2021-41163 | 1 Discourse | 1 Discourse | 2024-11-21 | 10 Critical |
Discourse is an open source platform for community discussion. In affected versions maliciously crafted requests could lead to remote code execution. This resulted from a lack of validation in subscribe_url values. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. To workaround the issue without updating, requests with a path starting /webhooks/aws path could be blocked at an upstream proxy. | ||||
CVE-2021-41140 | 1 Discourse | 1 Discourse Reactions | 2024-11-21 | 5.3 Medium |
Discourse-reactions is a plugin for the Discourse platform that allows user to add their reactions to the post.

CVE-2021-41095 | 1 Discourse | 1 Discourse | 2024-11-21 | 4.2 Medium |
Discourse is an open source discussion platform. There is a cross-site scripting (XSS) vulnerability in versions 2.7.7 and earlier of the `stable` branch, versions 2.8.0.beta6 and earlier of the `beta` branch, and versions 2.8.0.beta6 and earlier of the `tests-passed` branch. Rendering of some error messages that contain user input can be susceptible to XSS attacks. This vulnerability only affects sites which have blocked watched words that contain HTML tags, modified or disabled Discourse's default Content Security Policy. This issue is patched in the latest `stable`, `beta` and `tests-passed` versions of Discourse. As a workaround, avoid modifying or disabling Discourse’s default Content Security Policy, and blocking watched words containing HTML tags. |
