CVE-2026-40473

Описание

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.

A flaw was found in the camel-mina component of Apache Camel. This vulnerability allows a remote attacker to achieve arbitrary code execution by sending a specially crafted serialized Java object over the network to the MINA consumer port. The MinaConverter.toObjectInput type converter, used when a Camel route processes network input, fails to apply necessary security filters or class-loading restrictions during object deserialization. This oversight enables an attacker to execute malicious code within the application's context.
