CVE-2026-3775

CVE-2026-3775 affects Foxit PDF Editor/Reader (update service) and is due to the update check loading system libraries from a path that includes user-writable directories, not restricted to trusted system locations. This allows a local attacker with low privileges to place a malicious library tha...

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‑writab...

CVE-2026-3776

CVE-2026-3776 is a null pointer dereference in Foxit PDF Editor/Reader when handling stamp annotations that lack appearance (AP) data. The affected code dereferences the related object without checking for null/valid AP data, allowing a crafted PDF to crash the application and cause a denial of s...

CVE-2026-3776 Null pointer dereference in Foxit PDF Editor/Reader when accessing stamp annotation

The application does not validate the presence of required appearance AP data before accessing stamp annotation resources. When a PDF contains a stamp annotation missing its AP entry, the code continues to dereference the associated object without a prior null or validity check, which allows a...

CVE-2026-3780 Foxit PDF Editor/Reader Installer Uncontrolled Search Path Privilege Escalation

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...

CVE-2026-3780

CVE-2026-3780 concerns Foxit PDF Editor/Reader installers on Windows. The root cause is an installer that runs with elevated privileges while resolving system executables and DLLs using untrusted search paths that may include user-writable directories. This allows a local attacker to place malici...

CVE-2026-3778

CVE-2026-3778 affects Foxit PDF Editor/Reader (Foxit Reader) across platforms as described in connected records. The root cause is cyclic PDF object references created by pages and annotations referencing each other in a loop, which, when the document is processed by APIs that perform deep traver...

CVE-2026-3778 Stack exhaustion caused by cyclic references in Foxit PDF Editor/Reader

The application does not detect or guard against cyclic PDF object references while handling JavaScript in PDF. When pages and annotations are crafted that reference each other in a loop, passing the document to APIs e.g., SOAP that perform deep traversal can cause uncontrolled recursion, stack...
