CVE-2025-14913 identifies a missing authorization vulnerability (CWE-862) in the Frontend Post Submission Manager Lite – Frontend Posting WordPress plugin developed by wpshuffle. The flaw exists in the 'media_delete_action' function, which handles requests to delete media attachments. Due to improper authorization checks, unauthenticated attackers can invoke this function to delete arbitrary media files attached to the WordPress site. This vulnerability affects all plugin versions up to and including 1.2.6. The attack vector is network-based (AV:N), requiring no privileges (PR:N) or user interaction (UI:N), making it straightforward to exploit remotely. The impact is limited to integrity loss (I:L) without affecting confidentiality or availability. No patches or official fixes have been published yet, and no known exploits have been reported in the wild. The vulnerability could be leveraged to disrupt website content by removing images, videos, or other media, potentially damaging the site's appearance, user experience, or business operations. The vulnerability’s medium CVSS score (5.3) reflects moderate risk, balancing ease of exploitation with limited impact scope. Organizations using this plugin should monitor for updates and consider interim protective measures.

For European organizations, this vulnerability presents a risk of unauthorized deletion of media assets on WordPress sites using the affected plugin. This can lead to loss of important visual content, disruption of marketing materials, product images, or other media-dependent services, potentially harming brand reputation and user trust. Organizations in sectors such as e-commerce, media, education, and government that rely on WordPress for content management are particularly vulnerable. Although the vulnerability does not directly compromise confidentiality or availability, the integrity loss can cause operational disruptions and require resource-intensive recovery efforts. The ease of exploitation without authentication increases the threat level, especially for publicly accessible websites. Additionally, the absence of known exploits currently provides a window for proactive mitigation before active attacks emerge.

1. Monitor the plugin vendor’s official channels for security updates and apply patches immediately once available. 2. If a patch is not yet released, implement custom authorization checks in the plugin code or via WordPress hooks to restrict the 'media_delete_action' function to authenticated and authorized users only. 3. Limit media deletion capabilities to trusted roles such as administrators or editors through WordPress role management. 4. Regularly back up WordPress media libraries and database to enable quick restoration in case of unauthorized deletions. 5. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the vulnerable function. 6. Conduct security audits and penetration testing focused on WordPress plugins to identify similar authorization issues. 7. Educate site administrators about the risks of installing unverified plugins and encourage minimal plugin usage to reduce attack surface.
