CVE-2026-47065: Apache MINA Critical Deserialization Allow-list Bypass Vulnerability
CRITICALCVE-2026-47065 is a CRITICAL (CVSS 9.8) critical deserialization allow-list bypass vulnerability (CWE-502: Deserialization of Untrusted Data) affecting Apache MINA libraries in the Maven ecosystem. The issue involves critical deserialization allow-list bypass via resolveproxyclass. Remediation is available by upgrading affected packages to version 2.2.8, 2.1.13, 2.0.29.

Security Impact
CVSS: 9.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2026-47065
To remediate this vulnerability, upgrade all affected Apache MINA dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.mina</groupId>
<artifactId>mina-core</artifactId>
<version>2.2.8</version>
</dependency><dependency>
<groupId>org.apache.mina</groupId>
<artifactId>mina-core</artifactId>
<version>2.1.13</version>
</dependency><dependency>
<groupId>org.apache.mina</groupId>
<artifactId>mina-core</artifactId>
<version>2.0.29</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.minaHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-47065, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.minaAnalyze the terminal output to locate any version of Apache MINA in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.8), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.mina command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Apache MINA, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

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 .\n\n\nZDRES-233: Class.forName(name, initialize=true, classLoader) in readClassDescriptor Triggers Static Initialiser of Allow-Listed Classes\n\n\nAssessment: Fully addressed.\n\n\nFor 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 com.myapp.SomeClass ) causes <clinit> of SomeClass — and many real-world classes have side-effecting static initialisers\n\n\nBoth issues have been fixed.",
