A medium-severity cross-site request forgery in WP Hallo Welt from tikolan. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.1% (higher than 4% of all known vulnerabilities).
Official description
The WP Hallo Welt plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4. This is due to missing or incorrect nonce validation on the 'hallo_welt_seite' function. This makes it possible for unauthenticated attackers to update plugin settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Due to the insufficient input sanitization and output escaping, this can lead to Stored Cross-Site Scripting.
