Package        : roundcube
CVE ID         : CVE-2021-46144
Debian Bug     : 1003027

It was discovered that roundcube, a skinnable AJAX based webmail
solution for IMAP servers, did not properly sanitize HTML
messages. This would allow an attacker to perform Cross-Side Scripting
(XSS) attacks.

For the oldstable distribution (buster), this problem has been fixed
in version 1.3.17+dfsg.1-1~deb10u2.

For the stable distribution (bullseye), this problem has been fixed in
version 1.4.13+dfsg.1-1~deb11u1.

We recommend that you upgrade your roundcube packages.
