Summary

The A Simple Multilanguage Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'asmp-switcher' shortcode in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for 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.

Risk Assessment

An attacker with a contributor account can persistently inject malicious JavaScript into site pages, potentially leading to session theft, redirects, or compromise of an administrator's account visiting the infected page.

Recommendation

Update the A Simple Multilanguage Plugin to a version later than 1.0 or disable it if no fix is available, and limit the number of accounts with contributor privileges.
