      "value": "UnsafeAccessor (UA) is a bridge to access jdk.internal.misc.Unsafe & sun.misc.Unsafe. Normally, if UA is loaded as a named module, the internal data of UA is protected by JVM and others can only access UA via UA's standard API. The main application can set up `SecurityCheck.AccessLimiter` for UA to limit access to UA. Starting with version 1.4.0 and prior to version 1.7.0, when `SecurityCheck.AccessLimiter` is set up, untrusted code can access UA without limitation, even when UA is loaded as a named module. This issue does not affect those for whom `SecurityCheck.AccessLimiter` is not set up. Version 1.7.0 contains a patch."

La aplicaci\u00f3n principal puede configurar \"SecurityCheck.AccessLimiter\" para UA para limitar el acceso a UA. A partir de la versi\u00f3n 1.4.0 y versiones anteriores a 1.7.0, cuando es configurado \"SecurityCheck.AccessLimiter\", el c\u00f3digo que no es confiable puede acceder a la UA sin limitaciones, incluso cuando la UA es cargado como un m\u00f3dulo con nombre. Este problema no afecta a aquellos para los que no ha sido configurado \"SecurityCheck.AccessLimiter\". La versi\u00f3n 1.7.0 contiene un parche"
