CVE-2025-5988 is a medium-severity vulnerability identified in Red Hat Ansible Automation Platform 2, specifically within the aap-gateway component. The vulnerability arises due to the lack of Cross-Site Request Forgery (CSRF) origin checking on requests that the gateway sends to external components such as the controller, hub, and event-driven automation (EDA) modules. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged request to a web application, potentially causing unauthorized actions without the user's consent. In this case, the absence of origin validation means that malicious web pages or scripts could induce the gateway to perform unintended operations on connected components. The CVSS 3.1 base score of 5.3 reflects a medium severity, with the vector indicating network attack vector (AV:N), high attack complexity (AC:H), low privileges required (PR:L), no user interaction needed (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). This suggests that while the attacker needs some level of access (low privileges), they do not require user interaction, and the main risk is unauthorized disclosure of sensitive information. The vulnerability does not appear to have known exploits in the wild as of the publication date. Since Ansible Automation Platform is widely used for IT orchestration and automation, exploitation could lead to unauthorized information disclosure from critical automation infrastructure components, potentially exposing sensitive operational data or configuration details. However, the lack of integrity and availability impact reduces the risk of direct system manipulation or denial of service. No specific affected versions or patches are listed, indicating that users should verify their deployment versions and monitor vendor advisories for updates.

For European organizations, the impact of CVE-2025-5988 could be significant, especially for enterprises and public sector entities relying on Red Hat Ansible Automation Platform 2 for managing complex IT environments. Unauthorized disclosure of sensitive automation data could lead to exposure of internal workflows, credentials, or infrastructure details, which adversaries could leverage for further attacks or espionage. Given the critical role of automation in cloud deployments, DevOps pipelines, and hybrid IT environments, this vulnerability could undermine operational security and compliance with data protection regulations such as GDPR if sensitive personal or organizational data is exposed. The medium severity and requirement for low privileges mean that insider threats or compromised low-privilege accounts could exploit this flaw without needing to trick end users, increasing the risk surface. However, the absence of integrity and availability impacts limits the potential for direct sabotage or service disruption. Overall, the vulnerability poses a confidentiality risk that European organizations must address promptly to maintain secure automation practices and protect sensitive operational data.

To mitigate CVE-2025-5988, European organizations should implement the following specific measures: 1) Immediately review and restrict access privileges to the Ansible Automation Platform, ensuring that only trusted users have low-privilege accounts capable of interacting with the aap-gateway. 2) Monitor network traffic between the gateway and external components for unusual or unauthorized requests that could indicate exploitation attempts. 3) Employ web application firewalls (WAFs) or reverse proxies configured to enforce strict origin and referer header validation to block potential CSRF attempts targeting the gateway communications. 4) Segregate the network segments hosting the gateway and its external components to limit exposure to untrusted networks or users. 5) Stay current with Red Hat advisories and apply patches or updates as soon as they become available, even if no patch is currently listed, as vendors typically release fixes for such vulnerabilities. 6) Conduct security awareness training for administrators and users managing the automation platform to recognize and report suspicious activities. 7) Implement additional application-layer security controls such as multi-factor authentication and session management enhancements to reduce the risk of unauthorized access that could facilitate exploitation.
