      <title>CVE-2021-32656 — Trusted servers exchange can be triggered by attacker</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2021-32656</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; nextcloud security-advisories&lt;/p&gt;
&lt;p&gt;Nextcloud Server is a Nextcloud package that handles data storage. A vulnerability in federated share exists in versions prior to 19.0.11, 20.0.10, and 21.0.2. An attacker can gain access to basic information about users of a server by accessing a public link that a legitimate server user added as a federated share. This happens because Nextcloud supports sharing registered users with other Nextcloud servers, which can be done automatically when selecting the &amp;#34;Add server automatically once a federated share was created successfully&amp;#34; setting. The vulnerability is patched in versions 19.0.11, 20.0.10, and 21.0.2 As a workaround, disable &amp;#34;Add server automatically once a federated share was created successfully&amp;#34; in the Nextcloud settings.&lt;/p&gt;</description>
