CVE-2026-41727 (GCVE-0-2026-41727)

Vulnerability from cvelistv5 – Published: 2026-06-09 23:49 – Updated: 2026-06-27 21:15

Title

In Spring for Apache Kafka, forged retry topic headers subvert retry routing and backoff behavior

Summary

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.
