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.
