CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2025-14026 impacting forcepoint one_data_loss_prevention. Evaluated with CVSS Base Score of 7.8 (HIGH).

Original NVD Description

Source: NIST NVD
Forcepoint One DLP Client, version 23.04.5642 (and possibly newer versions), includes a restricted version of Python 2.5.4 that prevents use of the ctypes library. ctypes is a foreign function interface (FFI) for Python, enabling calls to DLLs/shared libraries, memory allocation, and direct code execution. It was demonstrated that these restrictions could be bypassed.
