CVE-2025-3588Public exploit

Code-generation crash via recursive root reference resolution

Published Apr 14, 2025 · Updated Apr 14, 2025

Denial of service in jsonschema2pojo 1.2.2 allows local users to crash code generation by processing a crafted JSON Schema. In SchemaRule.apply, a root $ref value of # resolves to the same schema, and the method calls itself again because that schema is never marked generated. The user must be able to supply a schema to a local Maven, CLI, or embedded invocation; the resulting StackOverflowError terminates that generation process without a demonstrated cross-process impact.
