Name of the Vulnerable Software and Affected Versions Wikilookup plugin for WordPress versions up to and including 1.1.5

Description The software is susceptible to Stored Cross-Site Scripting through the 'Popup Width' setting. Insufficient input sanitization and output escaping allow authenticated attackers with Administrator-level access or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page. This issue only affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations Update the Wikilookup plugin to a version later than 1.1.5.
