The Bug Library WordPress plugin before 2.1.2 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)
The Bug Library WordPress plugin before 2.1.1 does not check the file type on user-submitted bug reports, allowing an unauthenticated user to upload PHP files
The Bug Library WordPress plugin is vulnerable to Reflected Cross-Site Scripting via the successimportcount parameter found in the ~/bug-library.php file which allows attackers to inject arbitrary web scripts, in versions up to and including 2.0.3.
