Explain the intended input so visitors do not volunteer unnecessary sensitive material.","Make field limits consistent with the purpose. A very large free-text field or unnecessary upload option expands the information and resource-handling problem without necessarily improving lead quality.

Database queries need parameterization where applicable; text displayed in an administrator view needs encoding appropriate to that output context; authorization remains a separate check. A message that passes a length rule is not automatically safe for every downstream operation.","Review notification construction and integrations in their own context.

If it does, agree on useful file types and limits. A filename extension or browser-supplied content type is not sufficient proof of the file’s nature or safety. Consider processing tools, storage location, naming, download authorization and what happens when validation fails.","OWASP’s upload guidance calls for layered checks, size limits, controlled storage and access. Files may need appropriate scanning or content processing for the actual use case; no single check proves every document harmless. An uploaded file should not become executable website content or an unintended public URL.","Also inspect the next step. Automatically emailing an attachment creates another copy and passes risk to a recipient. Automatically opening or converting it introduces a processing dependency. Define who can retrieve it, how long it remains and how it is removed under the business-approved lifecycle.

Review of its browser event shows that the free-text message is also included in an analytics payload, although the business needs only an event count.
