CVE-2022-22150Public exploitNetwork attack vector

Code execution via mishandled nested JavaScript exception

Published Feb 4, 2022 · Updated Apr 15, 2025

Memory corruption in Foxit PDF Reader 11.1.0.52543 allows remote attackers to execute arbitrary code via a crafted PDF document. The getPageNthWordQuads JavaScript binding accepts a negative word index, throws during nested execution, then resumes with an inconsistent engine state that corrupts memory. Exploitation requires a user to open the document or visit a malicious site with the browser plugin enabled, and successful corruption executes code in the reader's process.
