CVE-2026-41727
Spring Kafka's retry topic infrastructure did not sufficiently validate user-controlled header values before acting on them.
Impact
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.
