Server-Side Request Forgery (SSRF)

CVE-2026-54514

Medium
5.3/10

Summary

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. In versions 2.0.0 prior to 2.18.8, 2.19.0 prior to 2.21.4 and 3.0.0 prior to 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.

CWE-918 - Server-Side Request Forgery (SSRF)

Server-side request forgery (SSRF) is a weakness that allows an attacker to send an arbitrary request, making it appear that the request was sent by the server. This request may bypass a firewall that would normally prevent direct access to the URL. The impact of this vulnerability can vary from unauthorized access to files and sensitive information to remote code execution.
