CVE-2026-6332

Protected source-code disclosure via cleartext project storage

Published May 14, 2026 · Updated May 14, 2026

Cleartext source-code storage in Schneider Electric EcoStruxure Machine Expert - HVAC before 1.10.0 allows local users to read protected source code. The project-storage mechanism retains protected application source in cleartext and exposes it when the software opens that source for editing or compilation. Access requires an authorized local session, and the reported consequence is limited to source-code confidentiality.
