jackson-core Has Potential for StackoverflowError if user parses an input file that contains very deeply nested data

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.

FasterXML jackson-core 安全漏洞

FasterXML jackson-core是FasterXML开源的一个API软件。 FasterXML jackson-core 2.15.0之前版本存在安全漏洞，该漏洞源于处理深度嵌套数据时可能导致堆栈溢出。
