## Bot detection with CrowdSec WAF

This release brings a major change to the CrowdSec WAF：a bot detection feature.

If enabled, clients will be served a challenge + fingerprinting page before accessing the website.
CrowdSec will evaluate the challenge and check the fingerprint against pre-configured rules to decide whether the client looks legitimate or not.

You can find more information about this new feature in [the documentation](https://docs.crowdsec.net/docs/next/appsec/bot_detection/intro).

Other notable changes include:
• A dedicated kubernetes datasource：crowdsec will fetch logs directly from the k8s apiserver
• New HTTP helpers for the expression language, to query external services from parsers and scenarios
• Performance improvements on the decisions stream endpoint in LAPI

## Security Notice

This release fixes 2 denial of service vulnerabilities in the HTTP and k8s-audit datasources:
• HTTP acquisition datasource lacks a decompressed body cap and trusts Content-Length：[GHSA-g2x2-jgfg-pg7g](https://github.com/crowdsecurity/crowdsec/security/advisories/GHSA-g2x2-jgfg-pg7g)
• Unbounded request-body read in kubernetes-audit acquisition webhook：[GHSA-rh69-4vqj-9gj8](https://github.com/crowdsecurity/crowdsec/security/advisories/GHSA-rh69-4vqj-9gj8)
