Foxit · Foxit Pdf Reader · CVE-2026-91803
**Name of the Vulnerable Software and Affected Versions**
Foxit PDF Editor/Reader (affected versions not specified)
**Description**
A local privilege escalation issue exists in the updater of Foxit PDF Editor/Reader. The problem occurs because the updater unsafely loads dynamic-link libraries (DLLs)—which are shared libraries used by multiple programs—from a directory that can be written to by a user during high-privilege operations. A local attacker can exploit this behavior to execute code with elevated privileges.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
