CVE-2026-91776

TypeDeserializerBase.findDeserializer in FasterXML jackson-databind caches the resolved deserializer under the raw, attacker-supplied type ID. When name-based polymorphism is configured with a fallback, for example @JsonTypeInfouse = Id.NAME, defaultImpl = ..., every distinct unrecognized type ID...

UBUNTU-CVE-2026-91777

Forward-reference completion for @JsonIdentityInfo object IDs in FasterXML jackson-databind performs a linear scan of the pending-reference accumulator for every resolved ID. The affected paths are CollectionDeserializer.CollectionReferringAccumulator.resolveForwardReference and the equivalent...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the findDeserializer method of TypeDeserializerBase, which caches every unknown type ID as a distinct key in the deserializers map even when all of them resolve to the same...
