CyberRota Analysis
AI-GeneratedThe Frontend Post Submission Manager Lite plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting due to inadequate input sanitization and output escaping in the post_content parameter. This flaw allows unauthenticated attackers to inject malicious scripts into pages, which execute when users access those pages, potentially compromising user data and site integrity. WordPress site operators using this plugin, especially those enabling guest post submissions, should prioritize immediate remediation to mitigate the risk of exploitation.
Original NVD Description
The Frontend Post Submission Manager Lite – Frontend Posting WordPress Plugin plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via post_content Parameter (data-label DOM Sink) in all versions up to, and including, 1.3.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the site operator to have enabled guest post submission via the [fpsm] shortcode, which registers a publicly accessible AJAX handler gated only by a nonce emitted on every page containing the shortcode.
