A.8.27 mandates security-by-design principles including distrust-external-input, data validation/sanitization, least privilege and security-oriented design reviews that can stop extraneous untrusted data from being treated as trusted, but this is only one slice of a weakness whose dominant causes sit in implementation and in specific input-handling code that the high-level engineering principles do not themselves enforce.

Secure coding standards mandate input sanitization and provenance checks that prevent acceptance of extraneous untrusted data.
