Improper Validation of Specified Quantity in Input

Overview Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input in the retrytopic-attempts header. An attacker can manipulate retry routing and backoff behavior by sending crafted headers with out-of-range attempt counts. Remediation Upgrade...

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 DelegatingDeserializer function. An attacker can exhaust system memory by sending records with unique, random spring.kafka.serialization.selector header values, leading to...

EUVD-2026-35908

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...

GHSA-XVFQ-4Q6Q-GXX7 In Spring for Apache Kafka, unbounded delegate cache keyed on user-controlled, potentially malicious selector header

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...

GHSA-XQ69-5H5V-X9X4 In Spring for Apache Kafka, overly broad trusted-package matching in header mappers exposes JDK classes to deserialization

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...

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...
