CVE-2025-14938 is a medium-severity vulnerability affecting the Listeo Core plugin for WordPress. This vulnerability allows unauthenticated arbitrary media uploads due to the absence of proper authorization and capability checks on the AJAX endpoint responsible for handling file uploads. With a CVSS score of 5.3, the risk to organizations includes unauthorized access to the site's media library, which can lead to potential misuse of uploaded content.
Organizations should prioritize patching this vulnerability as it poses a medium risk level. Although there is no confirmed public exploit available, the nature of the vulnerability may attract malicious actors seeking to exploit it. The urgency for defenders is to address this vulnerability in their priority patch cycle.
The vulnerability was disclosed on April 4, 2026, and affects all versions of the Listeo Core plugin up to and including version 2.0.27. Organizations utilizing this plugin should ensure they are running the latest version to mitigate this risk.
Additionally, the vulnerability falls under CWE-434, which relates to unvalidated file uploads. This classification highlights the importance of implementing strict validation controls on user-uploaded files to prevent unauthorized media from being uploaded.
Given the potential consequences of this vulnerability, organizations using the Listeo Core plugin should take immediate action to patch or mitigate the issue to prevent unauthorized media uploads.
Vulnerability Details
The Listeo Core plugin for WordPress is vulnerable to unauthenticated arbitrary media upload in all versions up to, and including, 2.0.27 via the "listeo_core_handle_dropped_media" function. This is due to missing authorization and capability checks on the AJAX endpoint handling file uploads. This makes it possible for unauthenticated attackers to upload arbitrary media to the site's media library, without achieving direct code execution.
Technical Analysis
The vulnerability is rooted in the failure to implement proper authorization checks on the AJAX endpoint managing media uploads. The attack vector is through network access, requiring no privileges or user interaction, which significantly lowers the barrier for potential exploitation. The attack complexity is low, as an attacker can exploit the vulnerability without any specialized skills.
The impacts of this vulnerability are limited to integrity, where unauthorized files may be uploaded, but there is no confidentiality or availability impact. Organizations should be aware of the potential for abuse of uploaded files, which could be used for phishing or spreading malware.
Risk & Impact Analysis
Organizations face a medium risk from the CVE-2025-14938 vulnerability in the Listeo Core plugin. The blast radius potential is significant, as unauthorized media uploads could lead to broader compromises. The urgency for organizations to address this vulnerability is classified as medium, meaning it should be included in the next patch cycle. Given that the CVSS score is 5.3, it highlights the need for prompt attention to avoid potential exploitation.
