V1.1 Encoding and Sanitization Architecture

In the sections below, syntax-specific or interpreter-specific requirements for safely processing unsafe content to avoid security vulnerabilities are provided. The requirements in this section cover the order in which this processing should occur and where it should take place. They also aim to ensure that whenever data is stored, it remains in its original state and is not stored in an encoded or escaped form (e.g., HTML encoding), to prevent double encoding issues.

V1.1.1 Verify that input is decoded or unescaped into a canonical form only once, it is only decoded when …	Verify that input is decoded or unescaped into a canonical form only once, it is only decoded when encoded data in that form is expected, and that this is done before processing the input further, for example it is not performed after input validation or sanitization.
V1.1.2 Verify that the application performs output encoding and escaping either as a final step before …	Verify that the application performs output encoding and escaping either as a final step before being used by the interpreter for which it is intended or by the interpreter itself.
