CVE-2025-6661 is a use-after-free vulnerability in PDF-XChange Editor that allows remote code execution when users open malicious PDF files or visit compromised websites. The vulnerability exploits improper object validation in App object handling, enabling attackers to execute arbitrary code with the privileges of the current user. With a CVSS score of 7.8 and local attack vector requiring user interaction, this represents a significant risk to PDF-XChange Editor users, particularly in environments where documents from untrusted sources are frequently processed.

CVE-2025-6660 is a heap-based buffer overflow vulnerability in PDF-XChange Editor's GIF file parsing engine that enables remote code execution with high severity (CVSS 7.8). The vulnerability affects users who open malicious GIF files or visit compromised web pages hosting malicious GIFs, requiring user interaction for exploitation. The flaw stems from inadequate validation of user-supplied data lengths before copying to fixed-length buffers, allowing attackers to overwrite heap memory and execute arbitrary code in the application's context.

CVE-2025-6659 is an out-of-bounds write vulnerability in PDF-XChange Editor's PRC file parser that allows remote code execution with high integrity and confidentiality impact (CVSS 7.8). The vulnerability affects PDF-XChange Editor users who open malicious PRC files or visit compromised websites, requiring user interaction but no special privileges. While the vulnerability demonstrates significant local exploitation potential, real-world risk depends on KEV/CISA status, EPSS probability data, and proof-of-concept availability, which would indicate active threat actor interest.

CVE-2025-6654 is an out-of-bounds write vulnerability in PDF-XChange Editor's PRC file parser that enables remote code execution with high severity (CVSS 7.8). The vulnerability affects PDF-XChange Editor installations when users open malicious PRC files or visit compromised web pages, allowing attackers to execute arbitrary code in the application's context. The vulnerability (formerly tracked as ZDI-CAN-26729) requires user interaction but poses significant risk due to the ubiquity of PDF applications and the high impact of code execution.

CVE-2025-6651 is a critical out-of-bounds write vulnerability in PDF-XChange Editor's JP2 image file parser that allows remote code execution when a user opens a malicious PDF or visits a malicious webpage containing an embedded JP2 file. The vulnerability (CVSS 7.8, formerly ZDI-CAN-26713) requires user interaction but results in arbitrary code execution with full process privileges. No public exploit code availability or active KEV status has been confirmed at this time, though the high CVSS and straightforward attack vector (local file opening) suggest meaningful real-world risk.

CVE-2025-6647 is a critical out-of-bounds write vulnerability in PDF-XChange Editor's U3D file parsing engine that enables remote code execution with high integrity and confidentiality impact (CVSS 7.8). The vulnerability affects users who open malicious PDF files or embedded U3D objects, requiring only user interaction to exploit. This is a memory corruption flaw in a widely-used PDF editor with moderate attack complexity, making it a practical threat to enterprise environments handling untrusted documents.

CVE-2025-6645 is a use-after-free vulnerability in PDF-XChange Editor's U3D file parser that allows remote code execution with high severity (CVSS 7.8). The vulnerability affects PDF-XChange Editor across multiple versions when processing malicious U3D-embedded PDF files; attackers can execute arbitrary code in the application's process context, requiring only user interaction to open a malicious file or visit a compromised webpage. The vulnerability was previously tracked as ZDI-CAN-26642 and represents a critical remote code execution risk for users of this widely-used PDF editor.

CVE-2025-6644 is a use-after-free vulnerability in PDF-XChange Editor's U3D file parser that allows remote code execution with high severity (CVSS 7.8). The vulnerability affects PDF-XChange Editor across multiple versions when processing malicious U3D-embedded PDF files or standalone U3D files, requiring only user interaction to exploit. The flaw stems from insufficient object validation before dereferencing, enabling attackers to execute arbitrary code in the application context; exploitation likelihood and active KEV status would indicate real-world threat priority.

CVE-2025-6642 is a critical out-of-bounds read vulnerability in PDF-XChange Editor's U3D file parser that allows remote code execution with user interaction. The vulnerability affects PDF-XChange Editor across multiple versions and stems from improper validation of U3D file data structures, enabling attackers to read beyond allocated memory boundaries and execute arbitrary code in the application's context. While this vulnerability currently shows a CVSS 7.8 score indicating high severity, real-world exploitation requires user interaction (opening a malicious PDF or visiting a malicious page), moderating immediate organizational risk.

CVE-2025-6640 is a use-after-free vulnerability in PDF-XChange Editor's U3D file parsing engine that allows remote code execution when a user opens a malicious PDF or visits a compromised webpage containing a specially crafted U3D file. The vulnerability stems from insufficient object validation before operations, enabling arbitrary code execution in the context of the affected application with high impact on confidentiality, integrity, and availability. This is a local attack vector requiring user interaction, with a CVSS score of 7.8 indicating high severity.
