GHSA-53w6-v7cv-fc9h Spring for Apache Kafka: Improper Validation of Retry Topic Header Values Leads to Retry Sequence Manipulation

• Maven org.springframework.kafka:spring-kafka: >= 4.0.0, < 4.0.6 → fixed in 4.0.6 • Maven org.springframework.kafka:spring-kafka: >= 3.3.0, < 3.3.16 → fixed in 3.3.16 • Maven org.springframework.kafka:spring-kafka: >= 3.2.0, <= 3.2.13 (no fix yet) • Maven org.springframework.kafka:spring-kafka: >= 2.9.0, <= 2.9.13 (no fix yet) • Maven org.springframework.kafka:spring-kafka: <= 2.8.11 (no fix yet)

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 retry_topic-attempts header to supply an out-of-range attempt count and cause the retry topic router to misidentify where the message was in the retry sequence. Affected versions: Spring for Apache Kafka 4.0.0 through 4.0.5; 3.3.0 through 3.3.15; 3.2.0 through 3.2.13; 2.9.0 through 2.9.13; 2.8.0 through 2.8.11.
