CVE-2026-83557

jackson-databind ships a default PolymorphicTypeValidator (DefaultBaseTypeLimitingValidator) used automatically when @JsonTypeInfo is present without a custom validator. The flaw: java.lang.Comparable was omitted from its "unsafe base types" deny-list, so isSafeSubType returned true unconditional...

CVE-2026-83557 jackson-databind omits java.lang.Comparable from DefaultBaseTypeLimitingValidator's unsafe base types

DefaultBaseTypeLimitingValidator is the PolymorphicTypeValidator applied automatically whenever @JsonTypeInfo is used without an explicitly configured custom validator. It denies polymorphic resolution only for a fixed set of "unsafe base types", and its isSafeSubType method returns true...

CVE-2026-77310

A flaw was found in jackson-databind. A remote attacker can exploit this vulnerability by providing specially crafted input during data deserialization, specifically when java.net.InetAddress objects are processed. This causes the application to perform eager DNS resolution on attacker-controlled...

Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection')

Overview Affected versions of this package are vulnerable to Use of Externally-Controlled Input to Select Classes or Code 'Unsafe Reflection' through NioPathDeserializer in src/main/java/com/fasterxml/jackson/databind/ext/NioPathDeserializer.java. An attacker can force readValue to resolve an...

Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection')
