"The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a
vulnerability as referenced in the SVD-2025-1103 advisory.

  - 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.
