Name of the Vulnerable Software and Affected Versions SEO Slider plugin for WordPress versions up to, and including, 1.1.0

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

Recommendations For versions up to, and including, 1.1.0, consider disabling the slider shortcode until a patch is available to prevent exploitation. Restrict access to post meta to minimize the risk of arbitrary web script injection. Avoid using user-supplied attributes in the affected shortcode until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
