High (7.5). EPSS 0.5% chance of exploitation in the next 30 days.
Advanced Installer before 22.6 has an uncontrolled search path element local privilege escalation vulnerability. When running as SYSTEM in certain configurations, Advanced Installer looks in standard-user writable locations for non-existent binaries and executes them as SYSTEM. A low-privileged attacker can place a malicious binary in a targeted folder; when the installer is executed, the attacker achieves arbitrary SYSTEM code execution.
