Base64-encoded data in parameter
Summary: PortSwigger Research notes that applications sometimes Base64-encode parameters to obfuscate them from users or to carry binary data. The presence of such encoded data may point to security-sensitive information or functionality that warrants further review for interesting content or additional entry points for malicious input.
Key Takeaway: Base64 encoding hides a parameter's contents from casual inspection but provides no real protection, so any sensitive value or input path sitting behind it is only as safe as the review you give it.
