Описание
The fix for CVE-2026-41635 was not applied to the 2.1.X and 2.2.X branches. Here was the original issue description:
Apache MINA's 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 before calling Class.forName().
Affected versions are Apache MINA 2.1.0 <= 2.1.11, and 2.2.0 <= 2.2.6.
The problem is resolved in Apache MINA 2.1.12, and 2.2.7 by
applying the classname allowlist earlier.
Affected are applications using Apache MINA that call IoBuffer.getObject().
Applications using Apache MINA are advised to upgrade.
A flaw was found in Apache MINA. An attacker can exploit a vulnerability in the AbstractIoBuffer.resolveClass() method, specifically when IoBuffer.getObject() is called, to bypass the classname allowlist. This bypass allows for the execution of arbitrary code, potentially leading to full system compromise.
Отчет
Red Hat products are affected by this vulnerability. However, the vulnerable code cannot be reached and therefore are not vulnerable. Due to this reason, this flaw has been rated with a low severity.
