0 CVE-2026-83557 is a deserialization vulnerability in FasterXML jackson-databind's default polymorphic type validator. The default validator denies polymorphic resolution only for nine specific unsafe base types but omits java.lang.Comparable, which is implemented by many classes. This omission allows applications using @JsonTypeInfo with Comparable-typed properties and no custom validator to accept type identifiers for any Comparable implementation, potentially enabling unsafe object creation such as java.io.File. The vulnerability affects multiple jackson-databind versions from 2.11.0 up to but excluding 3.2.2 in various ranges. No official patch or remediation guidance is provided in the input data.
