Last modified

CVE-2026-41862 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
