Name of the Vulnerable Software and Affected Versions The Simple post listing plugin for WordPress versions up to and including 0.2

Description The software is susceptible to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping of user-supplied attributes. Specifically, the 'class name' parameter within the postlist shortcode is affected. This allows authenticated attackers with contributor-level access or higher to inject malicious web scripts into pages. These scripts will execute when a user accesses the compromised page through mouse interaction.
