CVE-2026-54514— jackson-databind: InetSocketAddress deserialization triggers eager DNS resolution (SSRF)
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 2.0.0版本至2.18.8之前版本、2.19.0版本至2.21.4之前版本和3.0.0版本至3.1.4之前版本存在服务端请求伪造漏洞，该漏洞源于JDKFromStringDeserializer在反序列化时执行紧急DNS名称解析，可能导致应用在读取不受信任JSON时向攻击者选择的DNS发出查询。

Vulnerability Title
jackson-databind: InetSocketAddress deserialization triggers eager DNS resolution (SSRF)
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 2.0.0 until 2.18.8, 2.21.4, and 3.1.4, JDKFromStringDeserializer constructed InetSocketAddress with new InetSocketAddress(host, port), which performs eager DNS name resolution for hostname inputs at deserialization time. An application that binds untrusted JSON into a type containing an InetSocketAddress field issues an attacker-chosen DNS query during readValue, before any application-level validation or connect logic. The fix uses InetSocketAddress.createUnresolved(host, port), deferring DNS to an explicit connect. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4.
