CVE-2025-11724 is a critical vulnerability identified in the EM Beer Manager plugin for WordPress, affecting all versions up to 3.2.3. The root cause is the lack of proper file type validation in the EMBM_Admin_Untappd_Import_image() function combined with missing authorization checks on the wp_ajax_embm-untappd-import AJAX action. This flaw allows authenticated users with minimal privileges (subscriber-level and above) to upload arbitrary files, including executable PHP scripts, by exploiting the plugin's import functionality. The attack requires the attacker to set up a mock HTTP server that returns specific JSON data to facilitate the upload process. Once uploaded, these malicious files can be executed on the server, enabling remote code execution (RCE). This compromises the server’s confidentiality, integrity, and availability, potentially allowing full system compromise. The vulnerability has a CVSS v3.1 score of 8.8 (high severity), reflecting its ease of exploitation over the network without user interaction, requiring only low privileges. No official patches or fixes have been released yet, and no known exploits have been observed in the wild. The vulnerability is categorized under CWE-434 (Unrestricted Upload of File with Dangerous Type), a common and dangerous web application security issue. The plugin is used primarily in WordPress environments, which are widely deployed globally, making this vulnerability a significant risk for many organizations using this plugin for beer management or related hospitality services.

The impact of CVE-2025-11724 is severe for organizations using the EM Beer Manager plugin. Successful exploitation allows attackers to execute arbitrary code on the web server, leading to full system compromise. This can result in data theft, defacement, installation of backdoors, lateral movement within the network, and disruption of services. Since the vulnerability requires only subscriber-level access, an attacker could gain entry through weak or compromised credentials or by registering an account if registration is open. The lack of user interaction and network-level exploitability increases the risk of automated attacks and wormable scenarios. Organizations relying on WordPress for hospitality, craft beer management, or related services could face operational disruptions, reputational damage, and regulatory consequences if sensitive customer or business data is exposed or systems are taken offline. The absence of patches means the window of exposure remains open, increasing the urgency for mitigation.

Until an official patch is released, organizations should take immediate steps to mitigate risk. First, restrict or disable user registration and limit subscriber-level access to trusted users only. Implement strict monitoring and logging of file upload activities and AJAX requests related to the plugin. Use web application firewalls (WAFs) to detect and block suspicious upload attempts, especially those targeting the wp_ajax_embm-untappd-import action. Consider temporarily disabling or uninstalling the EM Beer Manager plugin if feasible. Employ network segmentation to isolate WordPress servers from critical infrastructure. Regularly audit user accounts and credentials to prevent unauthorized access. Once a patch is available, apply it promptly and verify the fix. Additionally, conduct thorough security assessments of WordPress plugins to identify similar risks and maintain an updated inventory of third-party components.
