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 typing is enabled and a type identifier contains generic parameters (i.e. the type ID string contains <), DatabindContext._resolveAndValidateGeneric() validates only the raw container class name (the substring before <) against the configured PTV. If the container type is approved, the method parses the full canonical type string via TypeFactory.constructFromCanonical() and returns the fully parameterized type without ever validating the nested type arguments against the PTV. The nested type arguments are then resolved, instantiated, and populated as beans during deserialization. An attacker who controls the type ID can therefore place a denied class as a generic type parameter of an allowed container — for example java.util.ArrayList<com.evil.Gadget> when only java.util.ArrayList is allow-listed. The container passes the PTV check; com.evil.Gadget is loaded via Class.forName(name, true, loader), instantiated, and its properties are set from attacker-controlled JSON. This completely bypasses an explicitly configured PTV allow-list. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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 typing is enabled
    and a type identifier contains generic parameters (i.e. the type ID string contains <),
    DatabindContext._resolveAndValidateGeneric() validates only the raw container class name (the substring
    before <) against the configured PTV. If the container type is approved, the method parses the full
    canonical type string via TypeFactory.constructFromCanonical() and returns the fully parameterized type
    without ever validating the nested type arguments against the PTV. The nested type arguments are then
    resolved, instantiated, and populated as beans during deserialization. An attacker who controls the type
    ID can therefore place a denied class as a generic type parameter of an allowed container — for example
    java.util.ArrayList<com.evil.Gadget> when only java.util.ArrayList is allow-listed. The container passes
    the PTV check; com.evil.Gadget is loaded via Class.forName(name, true, loader), instantiated, and its
    properties are set from attacker-controlled JSON. This completely bypasses an explicitly configured PTV
    allow-list. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4. (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.
