  "description": "Apache MINA\u0027s AbstractIoBuffer.resolveClass() contains two branches, one of them (for static classes or primitive types) does not check the class at all, bypassing the classname allowlist and allowing arbitrary code to be executed.     The fix checks if the class is present in the accepted class filter\u00A0before calling\u00A0Class.forName().\u00A0       Affected versions are Apache MINA 2.0.0 \u003C= 2.0.27, 2.1.0 \u003C= 2.1.10, and   2.2.0 \u003C= 2.2.5.      The problem is resolved in Apache MINA 2.0.28, 2.1.11, and 2.2.6 by  applying the classname allowlist earlier.      Affected are applications using Apache MINA that call\u00A0 IoBuffer.getObject().      Applications using Apache MINA are advised to upgrade.",
