CVE-2025-58337 is a security vulnerability classified under CWE-284 (Improper Access Control) affecting Apache Doris-MCP-Server version 0.1.0. The flaw allows an attacker who already possesses a valid read-only account to circumvent the server's read-only mode restrictions. Normally, read-only accounts should be prevented from making any modifications to the data or configuration. However, due to improper enforcement of access control policies, these accounts can perform unauthorized write operations, effectively escalating their privileges beyond intended limits. This vulnerability undermines the core security principle of least privilege and can lead to unauthorized data manipulation, potentially corrupting datasets or altering system configurations. The vulnerability was publicly disclosed on November 5, 2025, with no CVSS score assigned yet and no known exploits detected in the wild. The Apache Software Foundation has addressed the issue in Apache Doris-MCP-Server version 0.6.0, which operators are urged to deploy promptly. The vulnerability primarily affects installations running version 0.1.0, which may be present in environments relying on Apache Doris for large-scale data processing and analytics. Since the exploit requires valid read-only credentials, the attack vector involves either compromised or insider accounts. The lack of user interaction beyond authentication simplifies exploitation once credentials are obtained. This vulnerability threatens data integrity and confidentiality by enabling unauthorized modifications, which could have cascading effects on dependent systems and decision-making processes.

For European organizations, the impact of CVE-2025-58337 can be significant, particularly for those leveraging Apache Doris-MCP-Server in data analytics, business intelligence, or large-scale data processing infrastructures. Unauthorized modifications by attackers with read-only credentials can lead to data corruption, inaccurate analytics results, and potential disruption of business operations relying on trusted data. This can affect sectors such as finance, telecommunications, manufacturing, and public services, where data integrity is critical. Furthermore, unauthorized changes might facilitate further attacks or data exfiltration if attackers manipulate configurations or data access controls. The breach of access control also undermines compliance with European data protection regulations such as GDPR, which mandates strict controls over data integrity and access. Organizations may face reputational damage, regulatory penalties, and operational downtime if the vulnerability is exploited. Although no known exploits exist yet, the presence of this vulnerability in production environments increases risk exposure, especially if read-only credentials are shared or compromised. The impact on availability is limited, but the potential for integrity and confidentiality breaches is high.

To mitigate CVE-2025-58337, European organizations should immediately upgrade Apache Doris-MCP-Server installations from version 0.1.0 to version 0.6.0 or later, where the access control flaw has been fixed. In addition to patching, organizations should conduct a thorough audit of user accounts with read-only privileges to ensure that credentials have not been compromised or misused. Implement strict credential management policies, including multi-factor authentication (MFA) for all accounts, even those with read-only access, to reduce the risk of credential theft. Monitor system logs and audit trails for any unauthorized modification attempts or anomalous activities originating from read-only accounts. Employ network segmentation and least privilege principles to limit the scope of access for read-only users. Where feasible, implement additional application-layer access controls or data validation mechanisms to detect and prevent unauthorized changes. Regularly review and update access control policies to align with best practices and compliance requirements. Finally, maintain an incident response plan that includes procedures for addressing potential exploitation of this vulnerability.
