Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Spring for Apache Kafka (spring-kafka) versions from 4.0.0 to before 4.0.6, from 3.3.0 to before 3.3.16, 3.2.0 through 3.2.13, 2.9.0 through 2.9.13, and 2.8.11 and earlier are affected. An attacker who can send Kafka records to a topic that uses retry topics can add a crafted retry attempts header with an out-of-range value, causing the retry router to misidentify the message's position in the retry sequence. The source gives few details on the exact impact. Upgrade to 4.0.6 or 3.3.16, or to a later release in your line.
