# CVE-2026-63452

> 7.5 HIGH · 🧪 PoC

## Beschreibung

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the HTTP/1 parser limits decompression work per transaction but does not limit how many small brotli compression bombs a single flow can submit. With response-body-decompress-layer-limit enabled, repeated compressed responses make the decompression paths in rust/htp perform expensive work for every transaction, degrading packet processing and potentially causing loss of monitoring visibility or denial of service. This issue is fixed in version 8.0.6.
