This update for jackson-annotations, jackson-core, jackson-databind fixes the following issues - CVE-2026-54512: jackson-databind has a PolymorphicTypeValidator bypass via generic type parameters that allows arbitrary class instantiation bsc1268897. - CVE-2026-54513: jackson-databind has an array...

CVE-2026-54512

A flaw was found in jackson-databind. This vulnerability allows a remote attacker to bypass the PolymorphicTypeValidator PTV when polymorphic typing is enabled and a type identifier contains generic parameters. By crafting a malicious type ID, an attacker can place a denied class as a generic typ...

SUSE CVE-2026-54512

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.10.0 until 2.18.8, 2.21.4, and 3.1.4, jackson-databind's PolymorphicTypeValidator PTV is the primary safety mechanism guarding polymorphic deserialization. When polymorphic...

Linux Distros Unpatched Vulnerability : CVE-2026-54512

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.10.0 until 2.18.8, 2.21.4, and 3.1.4,...

Incomplete List of Disallowed Inputs

Overview Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs in the BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray method, which allowlists an array based only on clazz.isArray and does not validate the array's component type. An attacker who...

jackson-databind has an array subtype allowlist bypass in BasicPolymorphicTypeValidator (allowIfSubTypeIsArray)

Summary BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray allowlists any array type based only on clazz.isArray, without validating the array's component element type against the configured allowlist. A PTV built with allowIfSubTypeIsArray plus an explicit concrete-type allowlist...

Summary BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray allowlists any array type based only on clazz.isArray, without validating the array's component element type against the configured allowlist. A PTV built with allowIfSubTypeIsArray plus an explicit concrete-type allowlist...

GHSA-J3RV-43J4-C7QM jackson-databind has a PolymorphicTypeValidator bypass via generic type parameters that allows arbitrary class instantiation

jackson-databind's PolymorphicTypeValidator PTV is the primary safety mechanism guarding polymorphic deserialization. When polymorphic typing is enabled and a type identifier contains generic parameters i.e. the type ID string contains when only java.util.ArrayList is allow-listed. The container...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data in the DatabindContext.resolveAndValidateGeneric method, which validates only the raw container class of a type identifier against the configured PolymorphicTypeValidator and not its nested generic type...

Deserialization of Untrusted Data

Overview com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. Affected versions of this package are vulnerable to Deserialization of Untrusted Data in the...
