CVE-2026-41862 PUBLISHED

Assigner: vmware
Reserved: 22.04.2026 Published: 23.06.2026 Updated: 24.06.2026

Spring Statemachine's Kryo-based persistence backends (JPA, MongoDB, Redis and ZooKeeper) deserialise persisted state-machine contexts without enforcing a class allowlist (CWE-502, deserialisation of untrusted data), which can lead to remote code execution inside the application JVM.

Affected versions: Spring Statemachine 4.0.0 through 4.0.1 Spring Statemachine 3.2.0 through 3.2.4
