This attack occurs when XML input containing a reference to an external entity is processed by a weakly configured XML parser. This attack may lead to the disclosure of confidential data, DoS attacks, server-side request forgery, port scanning from the perspective of the machine where the parser is located, and other [which?] system impacts.

In XML-RPC, a client performs an RPC by sending an HTTP request to a server that implements XML-RPC and receives the HTTP response. A call can have multiple parameters and one result. The protocol defines a few data types for the parameters and result. Some of these data types are complex, i.e. nested.
Cross-site request forgery, also known as one-click attack or session riding and abbreviated as CSRF (sometimes pronounced sea-surf [1]) or XSRF, is a type of malicious exploit of a website or web application where unauthorized commands are submitted from a user that the web application trusts. [2]
Note that this template makes it clear that it "has" various Wikidata property elements, it does not automatically "use" the information stored in Wikidata – the VIDEOID, CHANNELID, HANDLE, USERNAME, SHOWID or PLAYLISTID alphanumeric parameters mentioned below must be entered by hand in the template.
The example attack consists of defining 10 entities, each defined as consisting of 10 of the previous entity, with the document consisting of a single instance of the largest entity, which expands to one billion copies of the first entity. In the most frequently cited example, the first entity is the string "lol", hence the name "billion laughs".
A reflected attack is typically delivered via email or a neutral web site. The bait is an innocent-looking URL, pointing to a trusted site but containing the XSS vector. If the trusted site is vulnerable to the vector, clicking the link can cause the victim's browser to execute the injected script.
