    Package        : tryton-server
    Version        : 5.0.4-2+deb10u2

    Edbo and Cedric Krier discovered that the Tryton application server does
    enforce record rules when only reading fields without an SQL type (like
    Function fields).

    For Debian 10 buster, this problem has been fixed in version
    5.0.4-2+deb10u2.

    We recommend that you upgrade your tryton-server packages.

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