| CVE-2021-41263 | 1 Discourse | 1 Rails Multisite | 2022-08-09 | 6.0 MEDIUM | 8.8 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-2022-31182 | 1 Discourse | 1 Discourse | 2022-08-08 | N/A | 5.3 MEDIUM |
| Discourse is the an open source discussion platform. In affected versions a maliciously crafted request for static assets could cause error responses to be cached by Discourse's default NGINX proxy configuration. A corrected NGINX configuration is included 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-2021-43792 | 1 Discourse | 1 Discourse | 2022-07-25 | 3.5 LOW | 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-2022-31096 | 1 Discourse | 1 Discourse | 2022-07-07 | 2.1 LOW | 5.7 MEDIUM |
| Discourse is an open source discussion platform. Under certain conditions, a logged in user can redeem an invite with an email that either doesn't match the invite's email or does not adhere to the email domain restriction of an invite link. The impact of this flaw is aggravated when the invite has been configured to add the user that accepts the invite into restricted groups. Once a user has been incorrectly added to a restricted group, the user may then be able to view content which that are restricted to the respective group. Users are advised to upgrade to the current stable releases. There are no known workarounds to this issue. | |||||
| CVE-2022-31060 | 1 Discourse | 1 Discourse | 2022-06-27 | 5.0 MEDIUM | 5.3 MEDIUM |
| Discourse is an open-source discussion platform. Prior to version 2.8.4 in the `stable` branch and version `2.9.0.beta5` in the `beta` and `tests-passed` branches, banner topic data is exposed on login-required sites. This issue is patched in version 2.8.4 in the `stable` branch and version `2.9.0.beta5` in the `beta` and `tests-passed` branches of Discourse. As a workaround, one may disable banners. | |||||
| CVE-2022-24866 | 1 Discourse | 1 Assign | 2022-05-06 | 4.0 MEDIUM | 4.3 MEDIUM |
| Discourse Assign is a plugin for assigning users to a topic in Discourse, an open-source messaging platform. Prior to version 1.0.1, the UserBookmarkSerializer serialized the whole User / Group object, which leaked some private information. The data was only being serialized to people who could view assignment info, which is limited to staff by default. For the vast majority of sites, this data was only leaked to trusted staff member, but for sites with assign features enabled publicly, the data was accessible to more people than just staff. Version 1.0.1 contains a patch. There are currently no known workarounds. | |||||
| CVE-2022-24824 | 1 Discourse | 1 Discourse | 2022-04-22 | 5.0 MEDIUM | 5.3 MEDIUM |
| Discourse is an open source platform for community discussion. In affected versions an attacker can poison the cache for anonymous (i.e. not logged in) users, such that the users are shown the crawler view of the site 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. There are no known workarounds for this issue. | |||||
| CVE-2022-24850 | 1 Discourse | 1 Discourse | 2022-04-22 | 4.0 MEDIUM | 4.3 MEDIUM |
| Discourse is an open source platform for community discussion. A category's group permissions settings can be viewed by anyone that has access to the category. As a result, a normal user is able to see whether a group has read/write permissions in the category even though the information should only be available to the users that can manage a category. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. There are no workarounds for this problem. | |||||
| CVE-2019-1020018 | 1 Discourse | 1 Discourse | 2022-04-18 | 7.5 HIGH | 7.3 HIGH |
| Discourse before 2.3.0 and 2.4.x before 2.4.0.beta3 lacks a confirmation screen when logging in via an email link. | |||||
| CVE-2022-24804 | 1 Discourse | 1 Discourse | 2022-04-18 | 5.0 MEDIUM | 5.3 MEDIUM |
| Discourse is an open source platform for community discussion. In stable versions prior to 2.8.3 and beta versions prior 2.9.0.beta4 erroneously expose groups. When a group with restricted visibility has been used to set the permissions of a category, the name of the group is leaked to any user that is able to see the category. To workaround the problem, a site administrator can remove groups with restricted visibility from any category's permissions setting. | |||||
| CVE-2022-24782 | 1 Discourse | 1 Discourse | 2022-04-07 | 4.0 MEDIUM | 4.3 MEDIUM |
| Discourse is an open source discussion platform. Versions 2.8.2 and prior in the `stable` branch, 2.9.0.beta3 and prior in the `beta` branch, and 2.9.0.beta3 and prior in the `tests-passed` branch are vulnerable to a data leak. Users can request an export of their own activity. Sometimes, due to category settings, they may have category membership for a secure category. The name of this secure category is shown to the user in the export. The same thing occurs when the user's post has been moved to a secure category. A patch for this issue is available in the `main` branch of Discourse's GitHub repository and is anticipated to be part of future releases. | |||||
| CVE-2022-23641 | 1 Discourse | 1 Discourse | 2022-02-24 | 4.0 MEDIUM | 6.5 MEDIUM |
| Discourse is an open source discussion platform. In versions prior to 2.8.1 in the `stable` branch, 2.9.0.beta2 in the `beta` branch, and 2.9.0.beta2 in the `tests-passed` branch, users can trigger a Denial of Service attack by posting a streaming URL. Parsing Oneboxes in the background job trigger an infinite loop, which cause memory leaks. This issue is patched in version 2.8.1 of the `stable` branch, 2.9.0.beta2 of the `beta` branch, and 2.9.0.beta2 of the `tests-passed` branch. As a workaround, disable onebox in admin panel completely or specify allow list of domains that will be oneboxed. | |||||
| CVE-2022-21677 | 1 Discourse | 1 Discourse | 2022-01-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| Discourse is an open source discussion platform. Discourse groups can be configured with varying visibility levels for the group as well as the group members. By default, a newly created group has its visibility set to public and the group's members visibility set to public as well. However, a group's visibility and the group's members visibility can be configured such that it is restricted to logged on users, members of the group or staff users. A vulnerability has been discovered in versions prior to 2.7.13 and 2.8.0.beta11 where the group advanced search option does not respect the group's visibility and members visibility level. As such, a group with restricted visibility or members visibility can be revealed through search with the right search option. This issue is patched in `stable` version 2.7.13, `beta` version 2.8.0.beta11, and `tests-passed` version 2.8.0.beta11 versions of Discourse. There are no workarounds aside from upgrading. | |||||
| CVE-2021-43850 | 1 Discourse | 1 Discourse | 2022-01-14 | 4.0 MEDIUM | 6.8 MEDIUM |
| Discourse is an open source platform for community discussion. In affected versions admins users can trigger a Denial of Service attack via the `/message-bus/_diagnostics` path. The impact of this vulnerability is greater on multisite Discourse instances (where multiple forums are served from a single application server) where any admin user on any of the forums are able to visit the `/message-bus/_diagnostics` path. The problem has been patched. Please upgrade to 2.8.0.beta10 or 2.7.12. No workarounds for this issue exist. | |||||
| CVE-2022-21642 | 1 Discourse | 1 Discourse | 2022-01-12 | 4.0 MEDIUM | 4.3 MEDIUM |
| Discourse is an open source platform for community discussion. In affected versions when composing a message from topic the composer user suggestions reveals whisper participants. The issue has been patched in stable version 2.7.13 and beta version 2.8.0.beta11. There is no workaround for this issue and users are advised to upgrade. | |||||
| CVE-2021-3138 | 1 Discourse | 1 Discourse | 2022-01-04 | 5.0 MEDIUM | 7.5 HIGH |
| In Discourse 2.7.0 through beta1, a rate-limit bypass leads to a bypass of the 2FA requirement for certain forms. | |||||
| CVE-2021-43827 | 1 Discourse | 1 Discourse Footnote | 2021-12-29 | 4.0 MEDIUM | 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-2021-43840 | 1 Discourse | 1 Message Bus | 2021-12-29 | 3.5 LOW | 6.5 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-2021-43794 | 1 Discourse | 1 Discourse | 2021-12-03 | 5.0 MEDIUM | 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. | |||||
