    Apache MINA: Critical Deserialization Allow-list Bypass via resolveProxyClass

    CVE-2026-47065 · GHSA-v3pr-hxpr-mfm8

    Affected
    • Maven org.apache.mina:mina-core >= 2.2.0, < 2.2.8; >= 2.1.0, < 2.1.13; < 2.0.29
    Fixed in

    Issue
    ZDRES-232: resolveProxyClass Not Overridden - acceptMatchers Filter Bypass via java.lang.reflect.Proxy Assessment: Fully addressed. When the serialised stream contains a TCPROXYCLASSDESC (the marker for a java.lang.reflect.Proxy ), JDK’s ObjectInputStream.readProxyDesc() is dispatched. JDK then calls the default ObjectInputStream.resolveProxyClass(interfaces) implementation, which performs Class.forName(intf, false, latestUserDefinedLoader()) for EACH interface name and constructs the proxy class — bypassing the accepted classes list . ZDRES-233: Class.forName(name, initialize=true, classLoader) in readClassDescriptor Triggers Static Initialiser of Allow-Listed Classes Assessment: Fully addressed. For ANY class on the allow-list, deserialising a stream that names it triggers the class’s (static initialiser) BEFORE any instance is constructed. This means an attacker who supplies a class name on the allow-list (e.g., the developer wrote accept(“com.myapp.") , attacker supplies…

    Apache MINA vulnerable to Deserialization of Untrusted Data (CVE-2026-41635 Incomplete Fix)

    CVE-2026-42779 · GHSA-vf5j-865m-mq7c

    Affected
    • Maven org.apache.mina:mina-core >= 2.1.0, < 2.1.12; >= 2.2.0, < 2.2.7
    Fixed in
    2.1.122.2.7· Vendor fix available
    Issue
    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.

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 static initializer in a class to be read might already have been executed. 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.

    Apache MINA Deserialization RCE Vulnerability

    CVE-2024-52046 · GHSA-76h9-2vwh-w278

    Affected
    • Maven org.apache.mina:mina-core >= 2.2.0, < 2.2.4; >= 2.1.0, < 2.1.10; >= 2.0.0-M1, < 2.0.27
    Fixed in
    2.2.42.0.272.1.10· Vendor fix available
    Issue
    The ObjectSerializationDecoder in Apache MINA uses Java’s native deserialization protocol to process incoming serialized data but lacks the necessary security checks and defenses. This vulnerability allows attackers to exploit the deserialization process by sending specially crafted malicious serialized data, potentially leading to remote code execution (RCE) attacks. This issue affects MINA core versions 2.0.X, 2.1.X and 2.2.X, and will be fixed by the releases 2.0.27, 2.1.10 and 2.2.4. It's also important to note that an application using MINA core library will only be affected if the IoBuffer#getObject() method is called, and this specific method is potentially called when adding a ProtocolCodecFilter instance using the ObjectSerializationCodecFactory class in the filter chain. If your application is specifically using those classes, you have to upgrade to the latest version of MINA core library. Upgrading will not be enough: you also need to explicitly allow the classes the…

    Cleartext Transmission of Sensitive Information in Apache MINA

    CVE-2019-0231 · GHSA-5h29-qq92-wj7f

    Affected
    • Maven org.apache.mina:mina-core <= 2.0.20; >= 2.1.0, <= 2.1.0
    Fixed in
    2.1.12.0.21· Vendor fix available
    Issue
    Handling of the closenotify SSL/TLS message does not lead to a connection closure, leading the server to retain the socket opened and to have the client potentially receive clear text messages afterward. Mitigation: 2.0.20 users should migrate to 2.0.21, 2.1.0 users should migrate to 2.1.1. This issue affects: Apache MINA.

    Recommended action: Upgrade to 2.1.1 or 2.0.21 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.

    Infinite loop in Apache MINA

    Fixed in
    2.1.52.0.22· Vendor fix available
    Issue
    In Apache MINA, a specifically crafted, malformed HTTP request may cause the HTTP Header decoder to loop indefinitely. The decoder assumed that the HTTP Header begins at the beginning of the buffer and loops if there is more data than expected. Please update MINA to 2.1.5 or greater.

    Recommended action: Upgrade to 2.1.5 or 2.0.22 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
