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...
