CVE-2026-47875Network attack vector

Remote code execution via trusted-type allowlist bypass

Published Aug 27, 2026 · Updated Aug 28, 2026

Unsafe deserialization in Spring Batch 5.2.0 through 5.2.6 and 6.0.0 through 6.0.4 allows remote attackers to execute arbitrary code. JobParameterDeserializer fails to enforce its trusted-types allowlist when Jackson2ExecutionContextStringSerializer processes attacker-controlled execution contexts, enabling known Jackson RCE gadgets. Exploitation requires an application to deserialize execution contexts from an untrusted job-repository data source.
