CVE-2026-54518 jackson-databind: @JsonView bypass for unwrapped creator parameters in jackson-databind

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and 3.1.4, UnwrappedPropertyHandler.processUnwrappedCreatorProperties replays buffered JSON into creator parameters but never consults...

CVE-2026-50193

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.13.0 until 2.14.0, a potential Denial-of-Service exists when attacker sends deeply nested JSON if and only if the service reads deeply nested 1000s of levels JSON as JsonNode...

CVE-2026-50193

jackson-databind contains a DoS in JSON tree handling: if a service reads deeply nested JSON (1000s of levels) via ObjectMapper.readTree() and then writes that JsonNode with toString(), it can consume significant resources. Affected are 2.13.0–2.14.0; fixed in 2.14.0. Mitigation: upgrade to 2.14....

CVE-2026-54512 jackson-databind: PolymorphicTypeValidator bypass via generic type parameters allows arbitrary class instantiation

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...

CVE-2026-54512

jackson-databind contains a PolymorphicTypeValidator (PTV) bypass vulnerability. When polymorphic typing is enabled and the type ID includes generic parameters, DatabindContext._resolveAndValidateGeneric() validates only the raw container class name, then parses the full canonical type without va...
