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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Red Hat build of Apache Camel for Spring Boot 4, Red Hat Fuse 7, Red Hat JBoss Enterprise Application Platform 7, Red Hat Single Sign-On 7 · no fix planned: Red Hat build of Apache Camel for Spring Boot 4, Red Hat Fuse 7, Red Hat JBoss Enterprise Application Platform 7, Red Hat Single Sign-On 7 · updated 2026-09-18 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-93572.json)","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":206826,"id":"CVE-2026-93572","ts":1789738971814,"field":"cvss","old":null,"new":"7.5"},{"seq":206825,"id":"CVE-2026-93572","ts":1789738971814,"field":"severity","old":"none","new":"high"}]}
