ShMapper by Teplitsa < 1.5.1 - Authenticated (Editor+) Stored Cross-Site Scripting

Description

The ShMapper by Teplitsa plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 1.5.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
