CVE-2026-3780
Foxit PDF Editor/Reader Installer Uncontrolled Search Path Privilege Escalation
CVSS Score
7.3
EPSS Score
0.0%
EPSS Percentile
2th
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.
