    Package        : designate
    CVE ID         : CVE-2026-71193 CVE-2026-71194

    Two security vulnerabilities were discovered in Designate, the OpenStack
    DNS-as-a-Service component, which could result in a tenant manipulating
    the zones of a different tenant, resulting in denial of service or DNS
    hijacking.

    For the stable distribution (trixie), these problems have been fixed in
    version 1:20.0.0-2+deb13u1.

    We recommend that you upgrade your designate packages.

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