CVE-2026-40473Apache Camel Mina: Unsafe Deserialization in MinaConverter.toObjectInput() via TCP/UDP
High 8.8
In plain English
A high-severity unsafe deserialization in Apache Camel Mina from Apache Software Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 1.2% (higher than 68% of all known vulnerabilities). Ready-made attack tooling exists: public proof-of-concept code. Fixed versions are available - upgrade the affected package.
Official description
The camel-mina component's MinaConverter.toObjectInput(IoBuffer) type converter wraps an IoBuffer in a java.io.ObjectInputStream without applying any ObjectInputFilter or class-loading restrictions. When a Camel route uses camel-mina as a TCP or UDP consumer and requests conversion to ObjectInput (for example via getBody(ObjectInput.class) or @Body ObjectInput), an attacker sending a crafted serialized Java object over the network to the MINA consumer port can trigger arbitrary code execution in the context of the application during readObject(). This issue affects Apache Camel: from 3.0.0 before 4.14.6, from 4.15.0 before 4.18.2, from 4.19.0 before 4.20.0. Users are recommended to upgrade to version 4.20.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.6. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.2.
