Answer in brief
CVE-2026-59693 records a Unknown severity vulnerability in CISA ADP Vulnrichment. The current sources do not mark it as known exploited. The current feed maps Siemens/Desigo DXR2 (generic), Siemens/Desigo PXC3 (generic), Siemens/Desigo PXC4 (generic), Siemens/Desigo PXC5.E003 (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A vulnerability has been identified in Desigo DXR2 (All versions < V01.21.233.16-7862), Desigo PXC3 (All versions < V01.21.233.16-7862), Desigo PXC4 (All versions < V02.21.194.36-2715), Desigo PXC5.E003 (All versions < V02.21.194.36-2715), Desigo PXC5.E24 (All versions < V02.21.194.36-2715), Desigo PXC7 (All versions < V02.21.194.36-2715). The affected devices are vulnerable to a denial-of-service (DoS) vulnerability. An attacker can exploit this issue by sending a malformed BACnet packet, causing the device to stop responding to BACnet queries. Recovery requires a device reset or reboot to restore normal functionality.
