Name of the Vulnerable Software and Affected Versions WP show more plugin for WordPress versions up to, and including, 1.0.7

Description The issue is related to Stored Cross-Site Scripting via the plugin's show more 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, which will execute whenever a user accesses an injected page.

Recommendations For WP show more plugin for WordPress versions up to, and including, 1.0.7, update to a version higher than 1.0.7 to resolve the issue. As a temporary workaround, consider restricting access to the show more shortcode for users with contributor-level access and above until a patch is available.
