CVE-2026-57248

Foxit · Foxit PDF Editor and Reader

A memory management vulnerability in Foxit PDF Editor and Reader allows for potential arbitrary code execution when processing malicious PDF files containing specifically crafted annotation attributes.

Executive summary

A high-severity memory management flaw in Foxit PDF Editor and Reader could allow attackers to execute arbitrary code through specially crafted PDF files.

Vulnerability

The application lacks sufficient object type and argument checking when JavaScript writes annotation attributes. This leads to the release of an invalid pointer or reference (CWE-763), which can be manipulated by an attacker to trigger memory corruption.

Business impact

With a CVSS score of 7.8, this vulnerability poses a significant risk to organizational assets. Successful exploitation allows an attacker to gain control over the application's memory space, potentially leading to unauthorized data access or total system compromise.

Remediation

Immediate Action: Apply the latest security updates provided by Foxit to address the identified memory management flaws.

Proactive Monitoring: Review security logs for suspicious PDF file activity or unusual application behavior that may indicate memory exploitation attempts.

Compensating Controls: Deploy endpoint protection solutions capable of detecting buffer overflows or memory-based attacks, and enforce strict application controls for untrusted PDF documents.

Exploitation status

Public Exploit Available: false

Analyst recommendation

The reliance on user interaction for exploitation does not diminish the severity of this vulnerability. Organizations should treat this as a high-priority update to ensure that memory safety mechanisms are properly implemented within the PDF rendering engine.
