    Package        : roundcube
    Version        : 1.4.15+dfsg.1-1+deb11u5
    CVE ID         : CVE-2025-49113
    Debian Bug     : 1107073

    Kirill Firsov discovered that Roundcube, a skinnable AJAX based webmail
    solution for IMAP servers, was performing PHP Object deserialization on
    unvalidated input, which could lead to remote code execution by an
    authenticated attacker.

    For Debian 11 bullseye, these problems have been fixed in version
    1.4.15+dfsg.1-1+deb11u5.

    We recommend that you upgrade your roundcube packages.

    For the detailed security status of roundcube please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/roundcube
