What is CVE-2025-52999?

The jackson-core library, utilized by the Jackson Data Processor, has a vulnerability related to the handling of deeply nested data structures. In versions before 2.15.0, parsing an input file with excessive nesting can lead to a StackOverflowError, disrupting application functionality. The updated version introduces a configurable depth limit, set by default to 1000 levels. If this limit is exceeded, a StreamConstraintsException will be thrown, preventing application crashes. Users are advised to avoid parsing untrusted input files as a precautionary measure.
