Apache MINA: Unsafe Deserialization (CWE-502) in JavaNativeMessageDecoder

Assigner: apache
Reserved: 28.10.2026 Published: 31.10.2026 Updated: 31.10.2026

UNSUPPORTED WHEN ASSIGNED 

JavaNativeMessageDecoder in the MINA 3.0 codec module calls ObjectInputStream.readObject() on frame bytes with no class filter, so an application that puts it in front of an untrusted peer is open to gadget-chain RCE.

As the 3.0.0 branch is inactive, we do not plan to release a version that fixes this issue.

Users are recommended to use the latest Apache MINA 2.2.X branch.
