CVE-2026-57244foxit software inc.foxit pdf editor+3
EPSS score0.17%
After JavaScript resetting the form, the synchronization process lacks re-entry protection and object lifecycle verification, resulting in the failure of the control pointer during the traversal process. After the pointer fails, it still continues to dereference, causing the application to crash.CVE-2026-57247foxit software inc.foxit pdf editor+3EPSS score0.17%
The application re-enters the document structure via field processing and deletes the current page, and then continues using the field objects obtained before deletion, triggering an illegal read and crashing.CVE-2026-57243foxit software inc.foxit pdf editor+3EPSS score0.15%
During the process of page opening and form formatting, a JavaScript reentrancy results in an inconsistent document status. Subsequently, with outdated page information, the application attempts to access invalid addresses, causing the application to crash.CVE-2026-57249foxit software inc.foxit pdf editor+3EPSS score0.17%
After the application opened the PDF file, the script first reset the annotation status, then triggered the reset form event by additional action. During the re-entry process, the application access invalid objects and crashed.CVE-2026-57239foxit software inc.foxit pdf editor+3EPSS score0.17%
The user-controllable executable files will be directly executed by high-privilege processes, allowing low-privilege users to have the opportunity to elevate their privileges to NT AUTHORITY\SYSTEM.CVE-2026-57242foxit software inc.foxit pdf editor+3EPSS score0.17%
The application opens the PDF, and JavaScript modifies the form. However, the related objects on the page lack complete lifecycle management and null value validation; when the page state changes, the application continuously dereferences invalid objects, eventually leading to a crash.CVE-2026-57256foxit software inc.foxit pdf editor+3EPSS score0.17%
When the application opens a PDF and executes JavaScript, it performs abnormal operations on the list box field, and this operation is repeated after the form is reset. During this process, the application failed to adequately verify the validity of the form objects and their internal dictionary pointers, resulting in accessing internal members of invalid or improperly initialized fields. This led to an illegal pointer read, ultimately causing the application to crash.CVE-2026-5941foxit software inc.foxit pdf editor+3EPSS score0.16%
Parsing logic flaws cause non-signature data to be misidentified as valid signatures when processing malformed form field hierarchies, leading to invalid memory writes and program crashes during internal data structure construction.CVE-2026-5940foxit software inc.foxit pdf editor+3EPSS score0.16%
Calling a function that triggers a UI refresh after removing comments via a script may access an invalidated object, leading to program crashes.CVE-2026-5942foxit software inc.foxit pdf editor+3EPSS score0.15%
Flaws in page lifecycle management allow document structure changes to desynchronize internal component states, causing subsequent operations to access invalidated objects and crash the program.CVE-2026-5943foxit software inc.foxit pdf editor+3EPSS score0.17%
Document structural anomalies caused inconsistencies between page element relationships and internal index states. When scripts triggered document modifications, object reference validity was not properly maintained, leading to a crash when accessing an invalid pointer during page information queries.CVE-2026-5937foxit software inc.foxit pdf editor+3EPSS score0.15%
Insufficient parameter verification leads to the occurrence of format errors in files, which will trigger an unhandled "std::invalid_argument" exception, ultimately causing the program to terminate.CVE-2026-5939foxit software inc.foxit pdf editor+3EPSS score0.16%
A crafted XFA PDF can trigger a use-after-free condition during calculate event processing, causing the application to crash and resulting in an arbitrary code execution.CVE-2026-5938foxit software inc.foxit pdf editor+3EPSS score0.15%
Improper control flow management allows a crafted document action chain to cause modal dialog reentry on the main thread, resulting in UI freeze and denial of service.CVE-2026-3777foxit software inc.foxit pdf editor+3EPSS score0.17%
The application does not properly validate the lifetime and validity of internal view cache pointers after JavaScript changes the document zoom and page state. When a script modifies the zoom property and then triggers a page change, the original view object may be destroyed while stale pointers are still kept and later dereferenced, which under crafted JavaScript and document structures can lead to a use-after-free condition and potentially allow arbitrary code execution.CVE-2026-3775foxit software inc.foxit pdf editor+3EPSS score0.19%
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.CVE-2026-3776foxit software inc.foxit pdf editor+3EPSS score0.15%
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 crafted document to trigger a null pointer dereference and crash the application, resulting in denial of service.CVE-2026-3778foxit software inc.foxit pdf editor+3EPSS score0.15%
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 exhaustion, and application crashes.CVE-2026-3779foxit software inc.foxit pdf editor+3EPSS score0.22%
The application's list box calculate array logic keeps stale references to page or form objects after they are deleted or re-created, which allows crafted documents to trigger a use-after-free when the calculation runs and can potentially lead to arbitrary code execution.CVE-2026-3780foxit software inc.foxit pdf editor+3EPSS score0.17%
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 legitimate system files, resulting in local privilege escalation.
