CVE-2026-91805

Name of the Vulnerable Software and Affected Versions Foxit PDF Editor/Reader (affected versions not specified)

Description An issue exists in the PDF page-tree handling. A specially crafted PDF can trigger page-structure changes during rendering, which causes the application to access released page objects. This leads to memory corruption and an application crash. Use-after-free is a condition where an application continues to use a pointer after it has been freed, which can be exploited to cause crashes or execute arbitrary code.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
