CVE-2026-47875
Last modified
CVE-2026-47875 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
