Source: CVE Database V5
Vendor/Project: Red Hat
Product: Red Hat Ansible Automation Platform 2.5 for RHEL 8

Description

A flaw was found in the EDA component of the Ansible Automation Platform, where user-supplied Git branch or refspec values are evaluated as Jinja2 templates. This vulnerability allows authenticated users to inject expressions that execute commands or access sensitive files on the EDA worker. In OpenShift, it can lead to service account token theft.

Technical Analysis

CVE-2025-49521 is a high-severity vulnerability found in the Event-Driven Ansible (EDA) component of Red Hat Ansible Automation Platform 2. The flaw arises because user-supplied Git branch or refspec values are processed and evaluated as Jinja2 templates without proper sanitization or validation. Jinja2 is a templating engine that allows embedding expressions and code execution within templates. By injecting malicious Jinja2 expressions, an authenticated attacker can execute arbitrary commands or access sensitive files on the EDA worker node. This represents a classic code injection vulnerability, where untrusted input is interpreted as executable code. In environments where Ansible Automation Platform is deployed on OpenShift, exploitation can escalate to theft of service account tokens, which are critical credentials used for authentication and authorization within the OpenShift cluster. The vulnerability has a CVSS 3.1 base score of 8.8, reflecting its high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and no user interaction required beyond authentication. Although no known exploits are currently reported in the wild, the vulnerability is publicly disclosed and requires immediate attention. The lack of available patches at the time of disclosure emphasizes the need for mitigation strategies until official fixes are released. This vulnerability highlights the risks of improper input handling in automation platforms that are widely used for orchestration and configuration management in enterprise environments.

Potential Impact

For European organizations, the impact of CVE-2025-49521 can be significant due to the widespread adoption of Red Hat Ansible Automation Platform in enterprise IT and cloud-native infrastructure management. Successful exploitation can lead to unauthorized command execution on critical automation infrastructure, potentially compromising the integrity and availability of automated workflows. In OpenShift deployments, the theft of service account tokens can allow attackers to move laterally within Kubernetes clusters, escalate privileges, and access sensitive workloads or data. This can disrupt business operations, lead to data breaches involving personal or proprietary information, and cause compliance violations under regulations such as GDPR. The automation platform often has elevated privileges and access to multiple systems, so compromise can cascade across the IT environment. Additionally, the vulnerability requires only authenticated access, which means insider threats or compromised credentials can be leveraged to exploit this flaw. European organizations relying on Ansible for continuous deployment, configuration management, or infrastructure as code are at risk of operational disruption and reputational damage if this vulnerability is exploited.

Mitigation Recommendations

1. Immediate mitigation should include restricting access to the EDA component of Ansible Automation Platform to only trusted and essential personnel to reduce the risk of exploitation by unauthorized users. 2. Implement strict authentication and authorization controls, including multi-factor authentication (MFA), to minimize the risk of credential compromise. 3. Monitor and audit usage of Git branch or refspec inputs within the EDA workflows to detect anomalous or suspicious template expressions. 4. Where possible, disable or limit the use of dynamic Jinja2 template evaluation on user-supplied inputs until a patch is available. 5. Employ network segmentation to isolate the Ansible Automation Platform and OpenShift clusters from less trusted networks. 6. Keep abreast of Red Hat security advisories and apply patches or updates promptly once released. 7. Review and harden OpenShift service account permissions to follow the principle of least privilege, reducing the impact of token theft. 8. Use runtime security tools to detect unusual command execution or file access patterns on EDA worker nodes. 9. Conduct internal security awareness to ensure users understand the risks of injecting untrusted inputs into automation workflows.
