  - The fix for CVE-2024-52046 in Apache MINA AbstractIoBuffer.getObject() was incomplete. The classname
    allowlist of classes allowed to be deserialized was applied too late after a static initializer in a class
    to be read might already have been executed. Affected versions are Apache MINA 2.0.0 <= 2.0.27, 2.1.0 <=
    2.1.10, and 2.2.0 <= 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
    IoBuffer.getObject(). Applications using Apache MINA are advised to upgrade (CVE-2026-41409)

Note that Nessus relies on the presence of the package as reported by the vendor.");
