    Package        : orthanc     Version        : 1.9.2+really1.9.1+dfsg-1+deb11u2     CVE ID         : CVE-2025-15581

    Orthanc versions before 1.12.10 are affected by an authorisation logic flaw in     the application's HTTP Basic Authentication implementation. Successful     exploitation could result in Privilege Escalation, potentially allowing full     administrative access.

    For Debian 11 bullseye, this problem has been fixed in version     1.9.2+really1.9.1+dfsg-1+deb11u2.

    We recommend that you upgrade your orthanc packages.
