Name of the Vulnerable Software and Affected Versions Music Sheet Viewer plugin for WordPress versions up to, and including, 4.1

Description The issue is related to Stored Cross-Site Scripting via the plugin's 'pn msv' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For Music Sheet Viewer plugin for WordPress versions up to, and including, 4.1: Update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the 'pn msv' shortcode to minimize the risk of exploitation. Avoid using user-supplied attributes in the 'pn msv' shortcode until the issue is resolved.
