CVE-2021-32782

Name of the Vulnerable Software and Affected Versions Nextcloud Circles versions prior to 0.19.14 Nextcloud Circles versions prior to 0.20.10 Nextcloud Circles versions prior to 0.21.3

Description The Nextcloud Circles application is vulnerable to a stored Cross-Site Scripting (XSS) issue. Due to the strict Content-Security-Policy shipped with Nextcloud, this issue is not exploitable on modern browsers supporting Content-Security-Policy. A notable exemption is Internet Explorer, which does not support Content-Security-Policy properly.

Recommendations For versions prior to 0.19.14, upgrade to 0.19.14 to resolve this issue. For versions prior to 0.20.10, upgrade to 0.20.10 to resolve this issue. For versions prior to 0.21.3, upgrade to 0.21.3 to resolve this issue. As a temporary workaround, users may use a browser that has support for Content-Security-Policy.
