Fix and mitigation
WAF and other mitigations
Can a WAF block it? Partly. Open redirects pass an outside URL in a parameter. A WAF can block external URLs in known redirect parameters.
Also consider: allow-list redirect targets
Based on the weakness type only; no CVE-specific evidence yet. We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.
