CVE-2026-1226

Local code execution via crafted TGML graphics

Published Feb 11, 2026 · Updated Feb 11, 2026

Code injection in Schneider Electric EcoStruxure Building Operation WorkStation and WebStation allows local users to execute code through TGML files. The applications execute untrusted or unintended code while processing maliciously crafted TGML design content; Schneider Electric has not disclosed the responsible parser or function. Exploitation requires low privileges, local access, and passive user interaction, and the resulting code runs within the affected application.
