CVE-2025-14026 is a high-severity flaw (CVSS 7.8) affecting one data loss prevention. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.
