Quick assessment
Affected
FasterXML jackson-databind
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
FasterXML jackson-databind是FasterXML组织开源的其中的一个具有数据绑定功能的组件。 FasterXML jackson-databind 2.13.0版本至2.14.0版本存在资源管理错误漏洞，该漏洞源于处理深度嵌套的JSON时，可能导致攻击者通过发送深度嵌套的JSON（如1000层嵌套数组，约2kB）作为JsonNode读取并输出，消耗大量资源，造成拒绝服务。

Vulnerability Title
jackson-databind: Deeply nested JsonNode throws StackOverflowError for toString()
Source: CVE Program / CVE List V5
Vulnerability Description
jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.13.0 until 2.14.0, a potential Denial-of-Service exists when attacker sends deeply nested JSON if (and only if) the service reads deeply nested (1000s of levels) JSON as JsonNode (ObjectMapper.readTree()) and writes out same (or modifided) node using JsonNode.toString(). This can consume significant amount of resources with concurrent relatively small requests (1000 nested arrays is 2kB). This vulnerability is fixed in 2.14.0.
