CVE-2025-48133 is a Missing Authorization vulnerability (CWE-862) found in the Uncanny Owl Uncanny Automator plugin, affecting versions up to and including 6.4.0.2. This vulnerability arises due to improperly configured access control mechanisms, allowing unauthorized users to perform actions or access functionalities that should be restricted. Specifically, the flaw lies in the failure to enforce proper authorization checks before executing certain operations within the plugin. Uncanny Automator is a WordPress automation plugin that enables users to create workflows connecting various plugins and external services. The vulnerability's CVSS 3.1 base score is 6.5 (medium severity), with the vector indicating that the attack can be performed remotely over the network (AV:N), requires no privileges (PR:N), and no user interaction (UI:N). The scope is unchanged (S:U), and the impact affects integrity and availability (I:L, A:L), but not confidentiality. This means an attacker can potentially manipulate or disrupt automated workflows, causing unauthorized changes or denial of service conditions within the WordPress environment. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was reserved on May 15, 2025, and published on June 5, 2025. Given the nature of the flaw, exploitation could allow attackers to bypass intended access restrictions, potentially leading to unauthorized workflow executions, data manipulation, or service disruptions within affected WordPress sites using this plugin.

For European organizations, especially those relying on WordPress sites with the Uncanny Automator plugin for business-critical automation, this vulnerability poses a moderate risk. Exploitation could lead to unauthorized changes in automated processes, potentially disrupting business operations, corrupting data integrity, or causing service outages. Organizations in sectors such as e-commerce, media, education, and government that use WordPress extensively for content management and automation may experience operational impacts or reputational damage if attackers manipulate workflows or cause downtime. Since the vulnerability does not directly expose confidential data but affects integrity and availability, the primary concerns are operational disruption and potential cascading effects on dependent systems. Additionally, organizations subject to strict regulatory requirements (e.g., GDPR) must consider the risk of unauthorized modifications and service interruptions impacting compliance and service continuity.

To mitigate this vulnerability, European organizations should: 1) Immediately audit their WordPress environments to identify installations of Uncanny Automator and verify the plugin version. 2) Apply any official patches or updates from Uncanny Owl as soon as they become available. 3) Until patches are released, restrict access to WordPress administrative interfaces and the plugin’s functionalities using network-level controls such as IP whitelisting or VPN access. 4) Implement strict role-based access controls within WordPress to limit who can configure or trigger automations. 5) Monitor logs for unusual activity related to automation workflows or unauthorized access attempts. 6) Consider temporarily disabling the Uncanny Automator plugin if it is not essential or if the risk is deemed unacceptable. 7) Educate site administrators about the risks of misconfigured access controls and encourage regular security reviews of plugin permissions and configurations. These steps go beyond generic advice by focusing on access restriction, monitoring, and proactive plugin management tailored to this specific vulnerability.
