A Secunia Advisory reports:

Secunia Research has discovered a vulnerability in Opera, which can be exploited by malicious people to conduct cross-site scripting attacks and retrieve a user's files.

The vulnerability is caused due to Opera allowing a user to drag e.g. an image, which is actually a "javascript:" URI, resulting in cross-site scripting if dropped over another site. This may also be used to populate a file upload form, resulting in uploading of arbitrary files to a malicious web site.

Successful exploitation requires that the user is tricked into dragging and dropping e.g. an image or a link.
