What does the canonical representation and its potential vulnerability to websites mean?

Question

I searched google for the meaning of canonical representation and discovered documents that are too cryptic. Can someone give a quick explanation of the canonical representation, as well as what are the typical vulnerabilities on sites for canonical representations?
