Over 50,000 WordPress websites are facing a critical security threat due to a vulnerability in the Uncanny Automator plugin, enabling authenticated users to execute privilege escalation attacks.This vulnerability, a concern for administrators who rely on maintaining secure WordPress ecosystems, allows subscribers with minimal access to elevate their privileges to the administrator level, presenting significant risks if not addressed promptly.

Critical Flaw Identified

Arbitrary File Upload Vulnerability

The vulnerability classified as CVE-2025-2075 stems from inadequate capability checks within the Uncanny Automator plugin’s code. Specifically, two primary functions—add_role() and user_role()—were found to mismanage user role assignments by failing to validate roles properly, thereby compromising the integrity of certain REST API endpoints.This flaw permits attackers to manipulate their roles through exposed endpoints using minimal effort due to lax security measures in the validate_rest_call() function.

Security researcher mikemyers brought the Arbitrary File Upload vulnerability to light on March 5, 2025, assigning it a high Common Vulnerability Scoring System (CVSS) score of 8.8, emphasizing its critical nature. The CVSS score quantifies the severity to ensure stakeholders understand the immediate need for corrective actions. Wordfence Intelligence, renowned for its security services, confirmed the proof-of-concept exploit, providing technical details of the problematic areas, thus validating the flaw’s potential for malicious exploitation.

Response and Mitigation

In response to the identified vulnerability, the development team at Uncanny Owl acted swiftly to mitigate the threat.On March 17, 2025, they released patch version 6.3.0.2 aimed at addressing the immediate concerns surrounding the plugin’s integrity. Subsequently, a fully resolved version—6.4.0—was made available on April 1, 2025, ensuring the complete eradication of the vulnerability.

Wordfence bolstered its protective measures by offering defense protocols to both premium and free users. Premium subscribers were shielded from the exploit from March 7, 2025, whereas free users received protection starting April 6, 2025. This proactive approach underscores the priority placed on maintaining security within digital landscapes, urging administrators to update their plugins urgently to safeguard against potential breaches.
