CVE-2026-93572

7.5 highEPSS 0.3%

High (7.5). EPSS 0.3% chance of exploitation in the next 30 days.

A flaw was found in Netty's `RedisArrayAggregator` component. A remote attacker can exploit this vulnerability by sending specially crafted nested Redis (RESP) array headers. This can cause the `RedisArrayAggregator` to eagerly preallocate a large amount of heap memory, leading to heap memory exhaustion and a Denial of Service (DoS) for applications using `RedisDecoder` with `RedisArrayAggregator` on untrusted traffic.
