Loading vulnerability…
CVE-2026-47065 is a critical unsafe deserialization vulnerability in Apache MINA's class-filtering logic. When a serialized stream contains a Java proxy class descriptor, Java ObjectInputStream dispatches proxy resolution to resolveProxyClass(). Without a MINA override that applies acceptMatchers validation to every proxy interface, the default JDK implementation loads the named interfaces and constructs the proxy class, bypassing MINA's accepted-classes allow list. A related class-descriptor path initialized allow-listed classes while resolving them, permitting execution of their static initializers before an instance was constructed.

A java.lang.reflect.Proxy-based acceptMatchers allow-list/filter bypass in Apache MINA. The stated fix is present in the 2.2.X branch, while the content reports that the 2.0.X and 2.1.X lines did not receive it.
A prior Apache MINA acceptMatchers allow-list filter bypass involving java.lang.reflect.Proxy and a missing resolveProxyClass() override. Its claimed fixes for the 2.0.x and 2.1.x maintenance branches were incomplete, which is the basis for CVE-2026-94301.
An Apache MINA acceptMatchers allow-list/filter bypass involving java.lang.reflect.Proxy and a missing resolveProxyClass() override. Its fix was applied to the 2.2.x branch but was not actually backported to the 2.0.x and 2.1.x branches as previously announced.
A critical Apache MINA core deserialization allow-list bypass involving resolveProxyClass. The advisory states that MINA core versions before 2.1.15 and 2.0.31 are affected and should be upgraded.
