    Package        : evolution-data-server
    Version        : 3.46.4-2+deb12u1
    CVE ID         : CVE-2026-2604
    Debian Bug     : 1128332

    An issue has been found in evolution-data-server, an evolution database backend
    server. A Flatpak application with D-Bus access to the addressbook service can
    delete arbitrary files on the host, potentially including Flatpak override
    files. This fix canonicalizes the file path before performing a prefix
    comparison, ensuring that ../ sequences are resolved.

    For Debian 12 bookworm, this problem has been fixed in version
    3.46.4-2+deb12u1.

    We recommend that you upgrade your evolution-data-server packages.

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