The vulnerability identified as CVE-2025-12058 affects the Keras deep learning framework, a widely used tool for building and deploying machine learning models. The flaw enables attackers to perform arbitrary file loading, which could lead to unauthorized access to sensitive files on the host system. Additionally, the vulnerability allows for server-side request forgery (SSRF) attacks, where an attacker can trick the server into making network requests to internal or external systems, potentially bypassing firewall restrictions or accessing internal services. The exact technical vector is not detailed, but typical SSRF and arbitrary file loading vulnerabilities arise from improper input validation or unsafe deserialization mechanisms within the software. No specific affected versions or patches have been disclosed yet, and no exploits have been observed in the wild. However, the vulnerability's presence in a popular AI framework raises concerns about the confidentiality and integrity of data processed by Keras applications, especially in environments where models handle sensitive or proprietary information. Exploitation likely does not require user interaction but may depend on the deployment scenario, such as exposed APIs or integration with web services. Given Keras's extensive use in research, industry, and cloud environments, this vulnerability could have broad implications if weaponized.

For European organizations, the vulnerability could lead to unauthorized disclosure of sensitive data, including intellectual property, personal data, or confidential research results processed by Keras models. SSRF attacks could be leveraged to pivot within internal networks, accessing other critical systems or services, potentially leading to broader compromise. Organizations in sectors such as finance, healthcare, automotive, and research institutions that rely heavily on AI/ML frameworks are at heightened risk. The impact extends to cloud-based AI deployments common in Europe, where multi-tenant environments could exacerbate the risk of lateral movement. Data privacy regulations like GDPR increase the stakes, as data exposure incidents could result in significant legal and financial penalties. The medium severity rating reflects the balance between the potential impact and the complexity of exploitation, but the absence of known exploits suggests a window for proactive defense.

Organizations should monitor official Keras and TensorFlow channels for security advisories and apply patches promptly once available. In the interim, restrict access to Keras-based services to trusted networks and users only, minimizing exposure to untrusted inputs. Implement strict input validation and sanitization on any interfaces interacting with Keras components to prevent injection of malicious payloads. Employ network segmentation and firewall rules to limit the ability of compromised systems to perform SSRF attacks against internal resources. Enable logging and monitoring for unusual file access patterns and outbound network requests originating from AI/ML infrastructure. Consider deploying runtime application self-protection (RASP) or web application firewalls (WAFs) that can detect and block SSRF attempts. Review deployment architectures to avoid exposing Keras services directly to the internet without proper authentication and authorization controls. Conduct security assessments and penetration testing focused on AI/ML pipelines to identify and remediate similar vulnerabilities.
