Alert meAnalysisAIv1 – Jul 08, 2026
Out-of-bounds memory access in Foxit PDF Editor and Foxit PDF Reader occurs when the application parses a malformed Unity 3D object embedded in a PDF, resolving attacker-influenced data as a pointer and dereferencing it as a valid address. A victim who opens a crafted PDF triggers the flaw (CVSS 7.8, UI:R), which manifests as a crash but, given the CWE-787 out-of-bounds write classification and High confidentiality/integrity/availability impact, carries potential for memory corruption and code execution in the context of the current user. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

DescriptionCVE.org
The application opened a PDF file containing an abnormal Unity 3D object. During parsing, the application incorrectly resolved a portion of the abnormal object as a pointer and used it as a valid address, ultimately causing the application to crash.
Executive ViewAI
Foxit PDF Editor and Reader are vulnerable to code execution through crafted PDF attachments with no available vendor patch. Organizations cannot safely process external PDFs using these products without risking system compromise and potential data breach-a significant exposure given PDF's centrality to business communication.
Within 24 hours: Issue mandatory security notice restricting PDF opening to internal sources; disable PDF auto-opening in email and messaging tools. Within 7 days: Complete inventory of Foxit deployments; pilot alternative PDF readers (Adobe Reader DC, Microsoft Edge). Within 30 days: Finalize remediation strategy (product replacement vs. sustained compensating controls); establish recurring monitoring of vendor advisory channels for patch release date.
No vendor-released patch identified at time of analysis. Block PDF attachments from external senders at email gateway; disable Foxit auto-opening and preview features; restrict usage to pre-validated internal PDFs only; implement application whitelisting to prevent unauthorized Foxit execution; require user security approval prior to opening external PDFs; establish weekly vendor advisory monitoring; conduct user training on PDF-based threats.

SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
