**Name of the Vulnerable Software and Affected Versions** Contests by Rewards Fuel plugin for WordPress versions up to, and including, 2.0.62 **Description** The issue is due to missing or incorrect nonce validation on the `ajax handler()` function, making it possible for unauthenticated attackers to update the plugin's settings and inject malicious JavaScript via a forged request. This can be achieved if an attacker can trick a site's user with the `edit posts` capability into performing an action such as clicking on a link. **Recommendations** For versions up to, and including, 2.0.62, update to a version higher than 2.0.62 to resolve the issue. As a temporary workaround, consider disabling the `ajax handler()` function until a patch is available.

**Name of the Vulnerable Software and Affected Versions** Contests by Rewards Fuel plugin for WordPress versions up to, and including, 2.0.64 **Description** The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages via the `update rewards fuel api key` parameter. These scripts will execute whenever a user accesses an injected page. **Recommendations** For versions up to, and including, 2.0.64, update to a version higher than 2.0.64 to resolve the issue. As a temporary workaround, consider restricting access to the `update rewards fuel api key` parameter to minimize the risk of exploitation.
