Impact assessment

CVE Assessment Mitigation without update
CVE-2026-31789 Not affected. The vulnerability only applies to 32-bit platforms. Additionally, the way OpenSSL is used in the affected container images does not expose any exploitable attack surface. No action required.
CVE-2026-43512 Not affected. Neither bluespice-pdfrenderer nor drawio use DIGEST authentication. Access to both services is anonymous by design. No action required.
CVE-2026-7261 Not affected. BlueSpice does not use a PHP SOAP server, and the affected SOAP_PERSISTENCE_SESSION setting is not in use. No action required.

Solution

No immediate action required. The affected libraries will be updated in the next regular release.
