Bot detection arrives in CrowdSec 1.8.0, along with two DoS fixes
CrowdSec 1.8.0 adds WAF bot detection via challenges and fingerprinting and fixes denial-of-service flaws in HTTP and Kubernetes audit datasources.
CrowdSec 1.8.0, released August 31, introduces bot detection in its WAF using client challenges and fingerprinting, plus fixes for two denial-of-service vulnerabilities in the HTTP acquisition datasource (unbounded decompressed body size, trusted Content-Length) and the Kubernetes audit webhook datasource (unbounded request body reads). The release also adds a dedicated Kubernetes datasource pulling logs directly from the apiserver, new HTTP helpers for external queries in the expression language, and performance work on the decisions stream endpoint. The challenge requires SSE4.1 and writable-executable memory, so some legitimate visitors may be blocked.
