Spring for Apache Kafka: Improper Validation of Retry Topic Header Values Leads to Retry Sequence Manipulation
Quick fix
GHSA-53w6-v7cv-fc9h — org.springframework.kafka:spring-kafka: upgrade to the fixed version with the command below.
# pom.xml: bump <version>4.0.6</version> for org.springframework.kafka:spring-kafkaDetails
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.
