CVE-2025-25208: Uncontrolled Resource Consumption
A Developer persona can bring down the Authorino service, preventing the evaluation of all AuthPolicies on the cluster
AI Analysis
Technical Summary
CVE-2025-25208 is a medium-severity vulnerability classified as uncontrolled resource consumption affecting Authorino version 1.0.1. Authorino is a service used to evaluate authorization policies (AuthPolicies) within a cluster environment, typically in Kubernetes or cloud-native infrastructures. The vulnerability allows an attacker with Developer-level privileges—meaning they have some authenticated access but not full administrative rights—to trigger resource exhaustion on the Authorino service. This exhaustion effectively causes a denial of service (DoS) by preventing the evaluation of all AuthPolicies across the cluster. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H) indicates that the attack can be launched remotely over the network with low attack complexity, requires privileges at the Developer level, and requires user interaction. The impact is limited to availability, with no direct confidentiality or integrity compromise. However, the disruption of AuthPolicy evaluation can halt authorization decisions, potentially blocking legitimate access or causing service outages for applications relying on Authorino for authorization enforcement. No known exploits are currently reported in the wild, and no patches or mitigations are linked yet. This vulnerability highlights the risk of insufficient resource management and input validation in authorization services that operate cluster-wide, emphasizing the need for strict access controls and resource limits on developer-facing interfaces.
Potential Impact
For European organizations, especially those adopting Kubernetes or cloud-native authorization frameworks using Authorino, this vulnerability poses a significant risk to service availability. Disruption of AuthPolicy evaluation can lead to widespread denial of access to critical applications and services, impacting business continuity and operational efficiency. Industries with stringent compliance requirements, such as finance, healthcare, and government sectors, may face regulatory scrutiny if authorization failures lead to service outages or data access issues. The medium severity reflects that while confidentiality and integrity are not directly impacted, the availability impact can cascade into operational disruptions and potential financial losses. Additionally, the requirement for Developer-level privileges means insider threats or compromised developer accounts could exploit this vulnerability, increasing the risk profile. Organizations relying on automated CI/CD pipelines or developer self-service portals integrated with Authorino are particularly vulnerable to exploitation attempts that could degrade cluster-wide authorization capabilities.
Mitigation Recommendations
To mitigate CVE-2025-25208, European organizations should implement the following specific measures: 1) Enforce strict role-based access control (RBAC) to limit Developer privileges strictly to necessary scopes, minimizing the risk of misuse. 2) Apply resource quotas and limits on the Authorino service pods to prevent resource exhaustion from any single user or process. 3) Monitor and log authorization evaluation metrics and resource usage to detect anomalous spikes indicative of exploitation attempts. 4) Implement network-level segmentation and firewall rules to restrict access to Authorino endpoints only to trusted developer networks or CI/CD systems. 5) Encourage developers to follow secure coding and usage practices to avoid triggering resource-intensive operations unintentionally. 6) Stay alert for official patches or updates from Authorino maintainers and apply them promptly once available. 7) Conduct regular security reviews and penetration tests focusing on authorization services to identify and remediate resource consumption weaknesses proactively.
