More information:

Denys Klymenko discovered a cross-site scripting (XSS) vulnerability in Roundcube, a skinnable AJAX based webmail solution for IMAP servers, which could allow a remote attacker to load arbitrary JavaScript code via a malicious text/html e-mail message with a crafted SVG document.

The issue is due to an incomplete fix for CVE-2020-16145.

For Debian 10 buster, this problem has been fixed in version 1.3.17+dfsg.1-1~deb10u4.

We recommend that you upgrade your roundcube packages.
