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.

  • GHSA-hgj6-7826-r7m5jackson-databind: InetSocketAddress deserialization triggers eager DNS resolution (SSRF)2026-06-23ghsa · osvUS

    ## Summary `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. ## Impact An attacker controlling JSON deserialized into an `InetSocketAddress`-bearing type can force outbound DNS lookups for attacker-chosen hostnames at deserialization time (SSRF / DNS-based out-of-band interaction / internal-resolver probing), purely from binding. ## Affected / Patched (verified via `git tag --contains` on `1f5a103`) - 2.18 line: `>= 2.18.0, < 2.18.8` -> fixed in **2.18.8** - 2.19-2.21 line: `>= 2.19.0, < 2.21.4` -> fixed in **2.21.4** - 3.x line: `>= 3.0.0, < 3.1.4` -> fixed in **3.1.4** ## Severity / CWE Maintainer: minor. Reporter: LOW. CWE-918 (SSRF). ## Upstream fix FasterXML/jackson-databind#5951 ("Improve InetSocketAddress deserialization"). Released 2026-06-04 in 2.18.8 / 2.21.4 / 3.1.4. ## Credits Omkhar Arasaratnam (@omkhar) - finder.
