Add a strong SECRET_KEY to your `superset_config.py` file like: SECRET_KEY = Alternatively you can set it with `SUPERSET_SECRET_KEY` environment variable. ## Edge WAF coverage (claimed by vendors, not measured) | Vendor | Status | First rule | Days after publication | |---|---|---|---| | Cloudflare | Before feed history | — | — | | AWS | No public claim | — | — | | Microsoft Azure | No public claim | — | — | | Google Cloud | Before feed history | — | — | | Fastly | Before feed history | — | — | | F5 | No public claim | — | — | | Akamai | No public source | — | — | | OWASP CRS | No public claim | — | — | ## Our test (measured) - OWASP Core Rule Set 4.25.0, paranoia level 1, anomaly threshold 5, default CRS settings: passed (0 of 1 requests blocked), template CVE-2023-27524, 2026-11-02 - OWASP Core Rule Set 4.25.0, paranoia level 2, anomaly threshold 5, default CRS settings: passed (0 of 1 requests blocked), template CVE-2023-27524, 2026-11-02 "No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed.
