CVE-2026-3780: Foxit PDF Editor/Reader Installer Uncontrolled Search Path Privilege Escalation

The application's installer runs with elevated privileges but resolves system executables and DLLs using untrusted search paths that can include user-writable directories, allowing a local attacker to place malicious binaries with the same names and have them loaded or executed instead of the legitimate system files, resulting in local privilege escalation.
