CVE-2026-77310

CVE-2026-77310 · jackson-databind: Eager DNS resolution (SSRF) still present in InetAddress deserialization (Incomplete fix for CVE-2026-54514)

This page contains facts from public vulnerability sources. Check the original advisory before updating.

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. Prior to versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1 on their respective release lines, the java.net.InetAddress branch of FromStringDeserializer.Std._deserialize() calls InetAddress.getByName() on attacker-controlled input, causing eager DNS resolution during deserialization and enabling DNS-based server-side request forgery and internal-host enumeration. This issue is fixed in versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1.
