Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

ClipShare is a lightweight and cross-platform tool for clipboard sharing. Prior to 3.8.5, ClipShare Server for Windows uses the default Windows DLL search order and loads system libraries like CRYPTBASE.dll and WindowsCodecs.dll from its own directory before the system path. A local, non-privileged user who can write to the folder containing clip_share.exe can place malicious DLLs there, leading to arbitrary code execution in the context of the server, and, if launched by an Administrator (or another elevated user), it results in a reliable local privilege escalation. This vulnerability is fixed in 3.8.5.
