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

We recommend that you upgrade your orthanc packages.
