Multiple vulnerabilities were discovered in roundcube, a skinnable AJAX
based webmail solution for IMAP servers, which could result in account
takeover, cross-site scripting, SSRF bypass, information disclosure or
denial of service.
For the stable distribution (trixie), these problems have been fixed in
version 1.6.17+dfsg-0+deb13u1.
We recommend that you upgrade your roundcube packages.
