jackson-core contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. From version 3.0.0 to before version 3.1.0, the UTF8DataInputJsonParser, which is used when parsing from a java.io.DataInput source, bypasses the maxNestingDepth constraint (default: 500) defined in StreamReadConstraints. A similar issue was found in ReaderBasedJsonParser. This allows a user to supply a JSON document with excessive nesting, which can cause a StackOverflowError when the structure is processed, leading to a Denial of Service (DoS). This issue has been patched in version 3.1.0.

A stack-based buffer overflow vulnerability exists in FasterXML jackson-core versions prior to 2.15.0. This occurs when parsing input files with deeply nested data, potentially causing a StackOverflowError. Version 2.15.0 introduces a configurable depth limit (default 1000) to prevent this issue by throwing a StreamConstraintsException when exceeded.jackson-databind also benefits from this fix as it relies on jackson-core for JSON parsing.
