    Package        : roundcube
    Version        : 1.4.15+dfsg.1-1+deb11u6
    CVE ID         : CVE-2025-68460 CVE-2025-68461
    Debian Bug     : 1122899

    Vulnerabilities were discovered in Roundcube, a skinnable AJAX based
    webmail solution for IMAP servers, which might lead to privilege
    escalation or information disclosure.

    CVE-2025-68460

        Information disclosure vulnerability in the HTML style sanitizer.

    CVE-2025-68461

        Cross-Site-Scripting (XSS) vulnerability via SVG's `<animate>` tag,
        which could allow a remote attacker to load arbitrary JavaScript
        code and might lead to privilege escalation or information
        disclosure via malicious SVG document.

    For Debian 11 bullseye, these problems have been fixed in version
    1.4.15+dfsg.1-1+deb11u6.

    We recommend that you upgrade your roundcube packages.
