This issue exists in all versions up to 2.6.1 due to insufficient input sanitization and output escaping on user-supplied attributes in the plugin's 'fshow' shortcode. Authenticated attackers with contributor-level access or higher can exploit this vulnerability to inject arbitrary web scripts, which will execute whenever a user accesses an injected page. Successful exploitation could lead to unintended website behavior or even data theft.
