- CVE-2026-96649, 30 Sep 2026
- 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. CVE record
- CVE-2026-1296, 18 Feb 2026
- The Frontend Post Submission Manager Lite plugin for WordPress is vulnerable to Open Redirection in all versions up to, and including, 1.2.7 due to insufficient validation on the 'requested_page' POST parameter in the verify_username_password function. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action such as clicking on a link. CVE record
- CVE-2025-14913, 26 Dec 2025
- The Frontend Post Submission Manager Lite - Frontend Posting WordPress Plugin plugin for WordPress is vulnerable to unauthorized loss of data due to an incorrect authorization check on the 'media_delete_action' function in all versions up to, and including, 1.2.6.

- CVE-2025-14080, 21 Dec 2025
- The Frontend Post Submission Manager Lite plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.2.5. This is due to missing authorization checks on the post update functionality in the fpsml_form_process AJAX action. This makes it possible for unauthenticated attackers to modify arbitrary posts by providing a post_id parameter via the guest posting form, allowing them to change post titles, content, excerpts, and remove post authors. CVE record
