    Package        : php-mongodb
    CVE ID         : CVE-2026-6811 CVE-2026-84968 CVE-2026-96745

    Multiple security vulnerabilities have been discovered in the MongoDB
    driver for PHP, which could result in information disclosure, PHP
    objection injection or denial of service.

    For the stable distribution (trixie), these problems have been fixed in
    version 2.0.0-1+deb13u1.

    We recommend that you upgrade your php-mongodb packages.

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