Hi,

The following vulnerability was published for jackson-core.

CVE-2025-52999[0]:
| jackson-core contains core low-level incremental ("streaming")
| parser and generator abstractions used by Jackson Data Processor. In
| versions prior to 2.15.0, if a user parses an input file and it has
| deeply nested data, Jackson could end up throwing a
| StackoverflowError if the depth is particularly large. jackson-core
| 2.15.0 contains a configurable limit for how deep Jackson will
| traverse in an input document, defaulting to an allowable depth of
| 1000. jackson-core will throw a StreamConstraintsException if the
| limit is reached. jackson-databind also benefits from this change
| because it uses jackson-core to parse JSON inputs. As a workaround,
| users should avoid parsing input files from untrusted sources.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
