CVE-2026-4769 Jul 13, 06:35 CRITICAL PATCH Act Now

Full system compromise of WAGO System I/O-Field series controllers (0765-xxx families) is possible when an unauthenticated remote attacker reaches an undocumented internal diagnostic interface that is briefly exposed during the device's early boot phase. Because the diagnostic capability requires no authentication and grants access to internal system processes, a successful attacker obtains complete control over confidentiality, integrity, and availability. Reported by CERT@VDE (VDE-2026-031); no public exploit code has been identified and it is not listed in CISA KEV at time of analysis.

CVE-2026-2328 Mar 30, 06:55 HIGH PATCH This Week

Path traversal in WAGO Device Sphere and Solution Builder allows unauthenticated remote attackers to access backend components and expose sensitive information. The vulnerability stems from insufficient input validation (CWE-790), enabling attackers to bypass intended access boundaries with low complexity over network vectors. CVSS 7.5 (High) reflects significant confidentiality impact. EPSS data unavailable; no public exploit identified at time of analysis, and CISA KEV status not confirmed.

CVE-2026-3587 Mar 23, 07:49 CRITICAL CISA Act Now

A hidden function in the CLI prompt of multiple WAGO industrial and lean managed switches allows unauthenticated remote attackers to escape the restricted interface and gain root access to the underlying Linux operating system. This results in complete device compromise with a maximum CVSS score of 10.0. The vulnerability affects over a dozen WAGO switch models used in industrial automation environments, and was disclosed by CERT@VDE.

Full system compromise of WAGO System I/O-Field series controllers (0765-xxx families) is possible when an unauthenticated remote attacker reaches an undocumented internal diagnostic interface that is briefly exposed during the device's early boot phase. Because the diagnostic capability requires no authentication and grants access to internal system processes, a successful attacker obtains complete control over confidentiality, integrity, and availability. Reported by CERT@VDE (VDE-2026-031); no public exploit code has been identified and it is not listed in CISA KEV at time of analysis.
