Featuring an impressive feature set with a user-friendly interface". Invision Power Top Site List is vulnerable to SQL injection vulnerability due to not properly sanitizing user input via the "offset" parameter. |

Vendor status:
The Invision Team was very prompt and professional in getting back to me about this. Because of the difficulty of exploitation there will be no patch or immediate upgrade released. However, the issue will be addressed in the next release of Invision Top Sites List.
