CVE-2025-0904 is a high-severity Out-of-bounds Read (CWE-125) vulnerability in Pdf-Xchange Pdf-Xchange Editor. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Malicious File (T1204.002); ranked at the 36.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the XPS parsing vulnerability by requiring timely flaw remediation through patching PDF-XChange Editor.
Addresses the root cause of insufficient validation of user-supplied data in XPS file parsing to prevent out-of-bounds reads.
Provides memory protections like address space randomization and non-executable memory to mitigate exploitation of the out-of-bounds read for information disclosure or code execution.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Out-of-bounds read in XPS parsing requires user to open malicious file (or visit page serving it), directly enabling T1204.002 User Execution: Malicious File for information disclosure.
NVD Description
PDF-XChange Editor XPS File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of PDF-XChange Editor. User interaction is required to exploit this vulnerability in that the target must visit a…

malicious page or open a malicious file. The specific flaw exists within the parsing of XPS files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-25422.
Deeper analysisAI
CVE-2025-0904 is an out-of-bounds read information disclosure vulnerability in PDF-XChange Editor, specifically within the parsing of XPS files. The flaw stems from insufficient validation of user-supplied data, allowing a read access past the end of an allocated object. This affects installations of PDF-XChange Editor, with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) and is associated with CWE-125 (Out-of-bounds Read).
Remote attackers can exploit this vulnerability to disclose sensitive information, but exploitation requires user interaction, such as the target visiting a malicious web page or opening a malicious file. While primarily enabling information disclosure, attackers can leverage this issue in conjunction with other vulnerabilities to achieve arbitrary code execution in the context of the affected process.
The Zero Day Initiative published details in advisory ZDI-25-071, originally tracked as ZDI-CAN-25422, which provides further technical analysis. Security practitioners should consult this advisory for mitigation guidance and patch information.
