Summary
UnsafeAccessor 1.4.0 until 1.7.0 has no security checking for UnsafeAccess.getInstance()
Details

Overview

Affected versions have no limit to using unsafe-accessor. Can be ignored if SecurityCheck.AccessLimiter not setup

Details

If UA was loaded as a named module, the internal data of UA will be protected by JVM and others can only access UA via UA's standard api. Main application can setup SecurityCheck.AccessLimiter for UA to limit accesses to UA. Untrusted code can access UA without lmitation in affected versions even UA was loaded as a named module.
