CVE-2026-1457

Authenticated code execution via unsanitized Web API input

Published Jan 29, 2026 · Updated Jan 29, 2026

Stack-based buffer overflow in the VIGI C485 V1 Web API before 3.1.1 Build 251124 Rel.50371n allows remote authenticated users to execute code. The vendor reports missing input sanitization in Web API buffer handling but does not identify the endpoint, input field, or unsafe copy operation. Exploitation requires high-privilege authentication from an adjacent network and yields elevated device code execution; the vendor advisory instead names C385 V1.
