Encrypted Query String Does Not Mean “Skip Validation”

A CloudPage trusts decrypted/request parameters directly for updates, preference changes or record access.

Evidence tier describes my hands-on relationship with the content. Official sources describe platform contracts/documentation. Production observations should not automatically be treated as official limits.

Why it bites

CloudPagesURL protects parameter values in an AES-GCM encrypted query string, but the landing page still needs to validate required values, record state and business authorization before changing data.

What to check
  1. Are required parameters present and structurally valid?
  2. Does the referenced record exist and belong to the expected workflow?
  3. Can repeated requests duplicate side effects?
Make it cheaper next time
  1. Use CloudPagesURL for private context from email.
  2. Treat RequestParameter values as inputs to validate before writes.
