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...

CVE-2026-42778

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

K000161244: Apache MINA vulnerabilities CVE-2026-42778 and CVE-2026-42779

Security Advisory Description CVE-2026-42778 The fix for CVE-2026-41409 was not applied to the 2.1.X and 2.2.X branches. 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...

Unsafe Deserialization

Apache MINA is vulnerable to Unsafe Deserialization. The vulnerability is due to delayed enforcement of the classname allowlist in AbstractIoBuffer.getObject, where deserialization via ObjectInputStream.readObject occurs before validation, allowing execution of static initializers in malicious...

Unsafe Deserialization

Apache MINA is vulnerable to Unsafe Deserialization. The vulnerability is due to incomplete enforcement of a classname allowlist in AbstractIoBuffer.resolveClass, where certain branches e.g., for primitive or static classes bypass validation and call Class.forName without checks, allowing attacke...

The vulnerability of the IoBuffer.getObject() function in the Apache MINA network-oriented Java framework allows a attacker to execute arbitrary code.

The vulnerability of the IoBuffer.getObject function in the Apache MINA network-oriented Java framework is related to deficiencies in the deserialization mechanism. Exploiting this vulnerability allows an attacker to execute arbitrary code...

Insecure Deserialization

org.apache.camel, camel-mina is vulnerable to insecure deserialization. The vulnerability is due to the MinaConverter.toObjectInputIoBuffer method wrapping untrusted data in a java.io.ObjectInputStream without applying filtering or class restrictions, which allows an attacker to send crafted...

Deserialization Of Untrusted Data

Apache MINA is vulnerable to deserialization of untrusted data. The vulnerability is due to missing class validation in the AbstractIoBuffer.resolveClass method, which bypasses the classname allowlist and allows an attacker to execute arbitrary code via crafted serialized input...
