CVE-2026-34023

Status: DeferredHigh (7.1)—

The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains an incorrect authorization vulnerability in the WebSocket communication used by the SafeController WebMessageBroker. An authenticated attacker with valid low-privileged branch user credentials can manipulate WebSocket messages by specifying controller identifiers belonging to other branches. This allows the attacker to access restricted functions and resources in other branches, including activating boxes outside of the user's authorized branch.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vector de red con privilegios (PR:L) indica T1210. Violación de autorización (CWE-863) permite eludir controles y acceder a recursos de otras ramas como usuario autenticado con bajo privilegio (T1078). La manipulación de mensajes WebSocket causa alteración de integridad (VI:H).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
