The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java permits ValueReader.readTable and ValueReader.readArray to call ValueReader.readFieldValue recursively for AMQP table type F and AMQP array type A values without a nesting-depth limit. A malicious AMQP server or network intermediary can send approximately 580 nested table levels in the pre-authentication connection.start frame, fitting within the default 131072-byte frame maximum, to trigger StackOverflowError. The error terminates the client input processing thread and causes denial of service. This issue is fixed in version 5.33.1.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-142329 advisory.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with
    RabbitMQ nodes. Prior to 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java permits
    ValueReader.readTable and ValueReader.readArray to call ValueReader.readFieldValue recursively for AMQP
    table type F and AMQP array type A values without a nesting-depth limit. A malicious AMQP server or
    network intermediary can send approximately 580 nested table levels in the pre-authentication
    connection.start frame, fitting within the default 131072-byte frame maximum, to trigger
    StackOverflowError. The error terminates the client input processing thread and causes denial of service.
    This issue is fixed in version 5.33.1. (CVE-2026-69220)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with     RabbitMQ nodes. Prior to 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java permits     ValueReader.readTable and ValueReader.readArray to call ValueReader.readFieldValue recursively for AMQP     table type F and AMQP array type A values without a nesting-depth limit.
