Spring for Apache Kafka: Improper Validation of Retry Topic Header Values Leads to Retry Sequence Manipulation

Spring Kafka's retry topic infrastructure did not sufficiently validate user-controlled header values before acting on them. A producer could send a record with a crafted retrytopic-attempts header to supply an out-of-range attempt count and cause the retry topic router to misidentify where the...

CVE-2026-41726: Allocation of Resources Without Limits or Throttling

When an application opts into DelegatingDeserializer, a producer can grow the consumer's heap without bound by sending records with unique random spring.kafka.serialization.selector header values, eventually causing GC thrash and OutOfMemoryError. Affected versions: Spring for Apache Kafka 4.0.0...

CVE-2026-41727: Improper Input Validation

Spring Kafka's retry topic infrastructure did not sufficiently validate user-controlled header values before acting on them. A producer could send a record with a crafted retrytopic-attempts header to supply an out-of-range attempt count and cause the retry topic router to misidentify where the...

CVE-2026-41731: Deserialization of Untrusted Data

JsonKafkaHeaderMapper and the deprecated DefaultKafkaHeaderMapper matched type headers against trusted packages using a prefix check, meaning that trusting any package implicitly trusted all of its subpackages. Combined with Jackson's default bean deserialization, a producer could supply crafted...
