What is CVE-2026-41862?

A vulnerability in Spring Statemachine allows for the deserialization of persisted state-machine contexts without enforcing a class allowlist. This oversight potentially exposes applications to remote code execution attacks, specifically through Kryo-based persistence backends such as JPA, MongoDB, Redis, and ZooKeeper. These can lead to serious security breaches if exploited.

Affected Version(s)

Spring Statemachine 4.0.0 < 4.0.1.1

Spring Statemachine 3.2.0 < 3.2.5
