Name of the Vulnerable Software and Affected Versions YourChannel plugin for WordPress versions up to, and including, 1.2.3

Description The issue is related to Cross-Site Request Forgery due to missing or incorrect nonce validation on the save function. This allows unauthenticated attackers to change the plugin's settings via a forged request if they can trick a site administrator into performing an action, such as clicking on a link.

Recommendations For versions up to, and including, 1.2.3, update to a version that includes proper nonce validation on the save function to prevent Cross-Site Request Forgery attacks. As a temporary workaround, consider restricting access to the plugin's settings page to minimize the risk of exploitation.
