This weakness impacts all versions of the plugin prior to 2.1.1, enabling unauthenticated attackers to potentially install and activate malicious plugins or upload files that masquerade as legitimate plugins. This poses a major risk for WordPress installations utilizing the GutenKit plugin, underscoring the critical need for immediate updates and robust security practices.
