Threats affecting pkg:maven/Apache Software Foundation/org.apache.camel:camel-mina

CVE-2026-85246 is a vulnerability in the Apache Camel Mina component where error messages containing sensitive information are sent back to remote peers. This occurs when processing an exchange fails, causing the Mina consumer to send the exception details, including class names, messages, and nested causes, over the network. This can expose internal deployment details such as class/package names, paths, hostnames, and connection information. The issue affects Apache Camel versions from 4.0.0 before 4.18.5 and from 4.19.0 before 4.22.1. The vulnerability is fixed in versions 4.18.5 and 4.22.1 by introducing a muteException option that suppresses sensitive exception details in replies. For those unable to upgrade immediately, a workaround involves adding an onException handler to prevent exception details from being sent to peers.

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.
