DLL search-order hijacking in Anthropic Claude for Windows installer (Claude Setup.exe) versions before 1.1.3363 enables local privilege escalation to system context. An attacker with low privileges and physical or local access can plant a malicious DLL (such as profapi.dll) in the installer directory; when an elevated user runs the installer, the uncontrolled search path causes the malicious DLL to be loaded and executed with system privileges, achieving arbitrary code execution. No public exploit code or active exploitation has been confirmed at the time of analysis.
