Fix and mitigation
WAF and other mitigations
Can a WAF block it? Partly. Code injection payloads are often obfuscated, so they slip past generic WAF rules.
Also consider: remove eval sinks · RASP
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.
