phpBB is vulnerable to a cross-site scripting vulnerability due to |
| 38 |
improper sanitization of user supplied input. Coupled with poor |

validation of BBCode URLs which may be included in a forum post, an |
| 40 |
unsuspecting user may follow a posted link triggering the |
| 41 |
vulnerability. |

|
| 46 |
Successful exploitation of the vulnerability could cause arbitrary |
