Description

Adding illegal characters (<...>) to some of the parameters of the ReferredPagesPlugin  are not properly escaped in the output of the plugin.

EG:

[{ReferredPagesPlugin page='"><svg onload=alert(/page_xss/)>' type='local|external|attachment' depth='1..8' include='regexp"><svg onload=alert(/include_xss/)>' exclude='regexp"><svg onload=alert(/exclude_xss/)>'}]
