AnalysisAIv1 – Jul 27, 2026

Privilege escalation to root via incorrect authorization in Progress LoadMaster, ECS Connection Manager, Object Scale Connection Manager, and MOVEit WAF allows an authenticated low-privilege attacker to fully compromise the affected appliance. Exploitation requires network adjacency to the management interface and low-privileged credentials, with no user interaction. No public exploit is identified, and there is no evidence of active exploitation at the time of analysis.
