Apache MINA: Apache MINA: Arbitrary code execution via classname allowlist bypass

A flaw was found in Apache MINA. A remote attacker could exploit a vulnerability in the AbstractIoBuffer.resolveClass method, which failed to properly validate class names for static classes or primitive types. This bypasses the intended security control, known as a classname allowlist, allowing ...

CVE-2026-42779

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...

Deserialization Vulnerability

Aache MINA is vulnerable to Unsafe Deserialization. The vulnerability is due to incomplete enforcement of a classname allowlist in AbstractIoBuffer.getObject, where deserialization occurs before validation, allowing execution of static initializers in malicious classes and potentially leading to...

CVE-2026-41409

A flaw was found in Apache MINA. An incomplete fix for a deserialization vulnerability in the AbstractIoBuffer.getObject method allowed a static initializer in a class to be executed before the classname allowlist was applied. This could enable a remote attacker to execute arbitrary code by sendi...

CVE-2026-42779

Here was the original issue 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 stat...

CVE-2026-42778

Apache MINA CVE-2026-42778 affects IoBuffer.getObject() deserialization. Affected: MINA 2.1.0–2.1.11 and 2.2.0–2.2.6 (also 2.1.0–2.1.110 in one note). Root cause: incomplete earlier fix for CVE-2024-52046; classname allowlist was applied too late. Impact: deserialization of untrusted data via IoB...
