Opera, possibly before 9.25, uses the HTTP Host header to determine the context of a document provided in a (1) 4xx or (2) 5xx CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an SSL tampering attack.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
