Upstream source description

Trendyol kafka-konsumer from 2.3.3 before 2.6.18 contains a denial of service vulnerability in batch_consumer.go that panics when a single record exceeds MessageGroupByteSizeLimit. Attackers able to produce to the consumed topic can publish one oversized record that terminates the consumer before offset commit, causing a persistent crash loop.
