Persistent Cross-Site Scripting in Economizzer Cashbook Entry

[Ron E <ronaldjedgerson () gmail com>]

A persistent cross-site scripting (XSS) vulnerability exists in gugoan's
Economizzer v.0.9-beta1 The application fails to properly sanitize
user-supplied input when creating a new cash book entry via the
*cashbook/create* endpoint. An attacker can inject malicious JavaScript
payloads that are permanently stored and later executed in the context of
any user who views the affected entry.
