CVE-2025-12683
NULL DACL assigned to Named Pipe communicating with SYSTEM Service
Description
The service employed by Everything, running as SYSTEM, communicates with the lower privileged Everything GUI via a named pipe. The named pipe has a NULL DACL and thus provides all users full permission over it; leading to potential Service Denial Of Service or Privilege escalation(only if chained with other elements) for a local low privilege user.
