Summary
A potential privilege escalation issue was identified in InstallShield version 2025 R2 and earlier when running compressed Basic MSI setup with Prerequisites from an insecure location. If a local administrator launches a compressed Setup.exe with Prerequisites from an unsecured location, the Prerequisite installers also might load from an unsecured location, potentially leading to privilege escalation.
