CVE-2026-41409 Details
Description
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
A deserialization vulnerability has been identified in Apache MINA versions 2.0.0 prior to 2.0.27, 2.1.0 prior to 2.1.10, and 2.2.0 prior to 2.2.5. The issue arises because the classname allowlist, which restricts deserialization to certain classes, was applied too late in the process. As a result, a static initializer in a class could have already executed before the allowlist was enforced. This vulnerability affects applications that use Apache MINA and call the IoBuffer.getObject() method.
Users are advised to upgrade to Apache MINA versions 2.0.28, 2.1.11, or 2.2.6, where this vulnerability has been addressed by applying the classname allowlist earlier in the deserialization process.
