## Technical details

The plugin improperly removes WordPress's wp_filter_post_kses security filter before inserting RSS feed content, allowing unauthenticated attackers to inject arbitrary HTML and JavaScript. Raw content from RSS feeds is only entity-decoded before storage, bypassing the sanitization that normally prevents script injection. An attacker with control over a subscribed RSS feed can inject persistent scripts that execute in the browser context of any user accessing the imported posts.
