      <title>CVE-2022-21677 — Group advanced search option may leak group and group's members visibility</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2022-21677</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; discourse&lt;/p&gt;
&lt;p&gt;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&amp;#39;s members visibility set to public as well. However, a group&amp;#39;s visibility and the group&amp;#39;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&amp;#39;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.&lt;/p&gt;</description>
