This is part 3 of the blog series in which we are introducing java functions for Spring Cloud Stream applications.

Other parts in the series.

Part 1 - General Introduction

Part 2 - Function Composition

In the last two blogs in this series, we provided a general introduction to this new initiative of migrating all the existing Spring Cloud Stream App Starters to functions and the various ways in which we can compose them. In this blog, we continue the series, showing how these functions are developed, tested, and used to generate Spring Cloud Stream applications. In particular, here we are focusing on how to write a supplier function (implementing java.util.function.Supplier…

Dear Spring community,

On behalf of the team and everyone who contributed, it is my pleasure to announce a number of maintenance releases for Spring Integration. Mostly these versions contain bug fixes and dependency upgrades.

CVE-2020-5413

The Spring Integration framework provides Kryo Codec implementations as an alternative for Java (de)serialization. When Kryo is configured with default options, all unregistered classes are resolved on demand. This leads to the "deserialization gadgets" exploit when the incoming data contains malicious code for execution during deserialization.

In order to protect against this type of attack, Kryo can be configured to require a set of trusted classes for (de)serialization. Spring Integration calls kryo.setRegistrationRequired(true); (trust no one) by default and pre-configures out-of-the-box Message<?> implementations as trusted classes. All other types have to be registered with Kryo using any available KryoRegistrar strategy injected into a PojoCodec…
