Multiple vulnerabilities were discovered in roundcube, a skinnable AJAX based webmail solution for IMAP servers, which could result in cross-site scripting, SSRF bypass, information disclosure, privilege escalation, denial of service or remote code execution.

For the stable distribution (trixie), these problems have been fixed in version 1.6.18+dfsg-0+deb13u1.

We recommend that you upgrade your roundcube packages.
