CVE-2026-3775 | Foxit PDF Editor/Reader Update Service Uncontrolled Search Path Element Local Privilege Escalation Vulnerability

The application's update service, when checking for updates, loads certain system libraries from a search path that includes directories writable by low‑privileged users and is not strictly restricted to trusted system locations. Because these libraries may be resolved and loaded from user‑writable locations, a local attacker can place a malicious library there and have it loaded with SYSTEM privileges, resulting in local privilege escalation and arbitrary code execution.

Base score Version Severity Vector Exploitability Impact Score source
7.8 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
