Abstract
------------------------------------------------------------------------
It was discovered that the Insert Html Snippet WordPress Plugin is
vulnerable to Cross-Site Request Forgery. Amongst others, this issue can
be used to update an existing HTML snippet. This can be used to insert
arbitrary HTML and scripting code within a post or page that uses the
snippet. In order to exploit this issue, the attacker has to lure/force
a logged on WordPress Administrator into opening a malicious website.

------------------------------------------------------------------------
Tested versions
------------------------------------------------------------------------
This issue was successfully tested on Insert Html Snippet WordPress
Plugin version 1.2.

------------------------------------------------------------------------
Fix
------------------------------------------------------------------------
This issue has been addressed in Insert Html Snippet version 1.2.1.
