kwebkitpart, kde-runtime -- insufficient input validation

Albert Aastals Cid reports:

kwebkitpart and the bookmarks:// io slave were not sanitizing input correctly allowing to some javascript being executed on the context of the referenced hostname.

Whilst in most cases, the JavaScript will be executed in an untrusted context, with the bookmarks IO slave, it will be executed in the context of the referenced hostname. It should however be noted that KDE mitigates this risk by attempting to ensure that such URLs cannot be embedded directly into Internet hosted content.
