Name of the Vulnerable Software and Affected Versions Private Comment plugin for WordPress versions prior to 0.0.5

Description The Private Comment plugin for WordPress is susceptible to Stored Cross-Site Scripting through the 'Label text' setting. Insufficient input sanitization and output escaping on the plugin’s label text option allows 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 impacts multi-site installations and installations where unfiltered html has been disabled.

Recommendations Update the Private Comment plugin to version 0.0.5 or later.
