Deserialization Flaw in Spring Batch Allows RCE

Publication date: 2026-08-27

Last updated on: 2026-09-02

Assigner: VMware

Description

Applications that deserialize execution contexts with Jackson2ExecutionContextStringSerializer are vulnerable to a deserialization attack if they use an untrusted data source for the job repository. The JobParameterDeserializer does not properly enforce the trusted-types allowlist, allowing an attacker to craft malicious input that can lead to arbitrary code execution, including known Jackson RCE gadgets. Spring Batch 6.0.0 - 6.0.4 Spring Batch 5.2.0 - 5.2.6

Attack-Flow Graph

Executive Summary

This vulnerability involves a deserialization attack in applications using Jackson2ExecutionContextStringSerializer with untrusted job repository data sources. The JobParameterDeserializer fails to enforce a trusted-types allowlist, allowing attackers to craft malicious input that can execute arbitrary code, including known Jackson RCE gadgets.

Detection Guidance

To detect this vulnerability, check if your system uses Spring Batch versions 6.0.0-6.0.4 or 5.2.0-5.2.6. Inspect job repositories for untrusted data sources and verify if Jackson2ExecutionContextStringSerializer is used for deserialization. No specific commands are provided in the context.

Impact Analysis

An attacker could exploit this to execute arbitrary code on your system, potentially leading to data breaches, system compromise, or unauthorized access. This is especially risky if your application processes untrusted data from external sources.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating GDPR's data protection requirements or HIPAA's safeguards for protected health information. Compliance may be compromised if the attack results in data breaches.

Mitigation Strategies

Upgrade to fixed versions of Spring Batch: 6.0.5 for OSS or 6.0.4.1 and 5.2.7 for Enterprise Support. No additional mitigation steps are required after upgrading.
