Server-side image validation provides an additional layer of security beyond Cloudflare's optimizations. Server-side validation can check for malicious content, ensure image file types are allowed, and enforce size limits that are stricter than Cloudflare's settings. This minimizes the risk of vulnerabilities arising from potentially malicious images bypassing Cloudflare's initial checks. It acts as a backup defense in case Cloudflare's defenses are circumvented.
