CVE-2025-6206 is a vulnerability classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) affecting the Aiomatic - Automatic AI Content Writer & Editor WordPress plugin developed by CodeRevolution. The issue arises from the 'aiomatic_image_editor_ajax_submit' function, which lacks proper validation of uploaded file types. Authenticated users with at least Subscriber-level privileges can exploit this flaw to upload arbitrary files to the server. A prerequisite for exploitation is the presence of a value in the Stability.AI API key field, but this value does not need to be valid, lowering the barrier to attack. Once arbitrary files are uploaded, attackers may execute remote code, potentially taking full control of the hosting environment. The vulnerability affects all versions up to 2.5.0, with no patches currently available. The CVSS v3.1 base score is 7.5, reflecting high severity due to network attack vector, low attack complexity, low privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. Although no known exploits are reported in the wild, the combination of AI content generation capabilities and remote code execution risk makes this a critical concern for WordPress sites leveraging Aiomatic for AI-driven content and chatbot services.

The potential impact of CVE-2025-6206 is severe for organizations using the Aiomatic plugin. Successful exploitation can lead to remote code execution, allowing attackers to execute arbitrary commands on the web server. This can result in full system compromise, data theft, defacement, or use of the server as a pivot point for further attacks within the network. Confidentiality is at risk due to possible data exposure; integrity can be compromised through unauthorized modifications; and availability may be affected by service disruption or destruction of data. Since the vulnerability requires only Subscriber-level access, which is a low privilege role in WordPress, the attack surface is broad, especially on sites allowing user registrations or multiple contributors. The requirement of an arbitrary Stability.AI API key value does not significantly hinder exploitation. Organizations relying on Aiomatic for AI content creation or chatbot functionality face increased risk of reputational damage, regulatory penalties, and operational disruption if exploited.

To mitigate CVE-2025-6206, organizations should immediately restrict access to the Aiomatic plugin functions to trusted users only, preferably limiting Subscriber-level users from uploading files until a patch is available. Administrators should remove or disable the Stability.AI API key value if not in use, as this is a prerequisite for exploitation. Implement additional server-side file type validation and filtering to block dangerous file uploads, such as executable scripts or web shells. Employ web application firewalls (WAFs) with rules targeting suspicious upload patterns related to this plugin. Monitor server logs for unusual file upload activity or unexpected API key usage. Regularly audit user roles and permissions to minimize the number of users with upload capabilities. Stay alert for official patches or updates from CodeRevolution and apply them promptly once released. Consider isolating WordPress instances or running them with least privilege to limit the impact of potential compromises.
