M.Neset KABAKLI has discovered a vulnerability in UebiMiau, which can be exploited by malicious people to conduct script insertion attacks.

The vulnerability is caused due to UebiMiau failing to properly sanitise the contents of HTML emails. This can be exploited to include arbitrary JavaScript, which will be executed in a user's browser session in context of the UebiMiau server, as soon as the user views a received email.

Example:
<img src="javascript:[code];" />

The vulnerability has been confirmed in 2.7.9. Other versions may also be affected.

Solution
Update to version 2.7.10.
