CVE-2025-59333 is a high-severity vulnerability (CVSS 8.1) affecting the executeautomation mcp-database-server version 1.1.0 and earlier, specifically the npm package distribution @executeautomation/database-server. The core issue is an improper access control flaw (CWE-284) where the server fails to enforce a "read-only" mode adequately. This means that although the server is expected to restrict certain operations to read-only access, the security controls are insufficient, allowing an attacker with some level of privileges (requires low privileges, PR:L) to perform unauthorized actions. The vulnerability is network exploitable (AV:N) without user interaction (UI:N), and it impacts confidentiality and availability but not integrity, as per the CVSS vector. The affected component is primarily used as a database server interface, notably with PostgreSQL and potentially other database systems that expose elevated functionalities through this server. Exploitation could lead to denial of service (DoS) conditions and other unexpected behaviors, such as unauthorized data exposure or disruption of database availability. The vulnerability is limited to the npm package distribution; other distributions of the mcp-database-server are not affected. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that remediation might still be pending or in development. The vulnerability was published recently in September 2025, suggesting that organizations using this package should prioritize assessment and mitigation promptly.

For European organizations, the impact of CVE-2025-59333 can be significant, especially for those relying on the npm-distributed mcp-database-server in their infrastructure. The vulnerability allows attackers with low privileges to bypass intended read-only restrictions, potentially leading to denial of service and unauthorized data exposure. This can disrupt critical business operations, particularly in sectors heavily dependent on database availability and confidentiality, such as finance, healthcare, and government services. Given the network-exploitable nature of the flaw, attackers could remotely target vulnerable servers, increasing the risk of widespread disruption. The lack of integrity impact reduces the risk of data tampering but does not eliminate concerns about data confidentiality and service availability. European organizations with PostgreSQL or other affected database systems interfaced via this server are at risk of operational downtime and potential leakage of sensitive information. The absence of known exploits in the wild provides a window for proactive mitigation, but the high CVSS score indicates that the threat should be taken seriously to avoid potential future exploitation.

1. Immediate assessment of all systems using the @executeautomation/database-server npm package version 1.1.0 or earlier is critical. Identify and inventory all instances to understand exposure. 2. Where possible, upgrade to a fixed version once available from the vendor or consider switching to alternative distributions of the mcp-database-server that are not affected by this vulnerability. 3. Implement network-level controls such as firewall rules and segmentation to restrict access to the mcp-database-server instances only to trusted hosts and networks, minimizing exposure to external attackers. 4. Enforce strict authentication and authorization policies on the database and server layers to limit the privileges of users and services interacting with the mcp-database-server. 5. Monitor logs and network traffic for unusual activities indicative of exploitation attempts, such as unexpected write operations or service disruptions. 6. Consider deploying Web Application Firewalls (WAFs) or Intrusion Detection/Prevention Systems (IDS/IPS) with rules tailored to detect and block exploitation patterns targeting this vulnerability. 7. Engage with the vendor or community to track patch releases and apply updates promptly once available. 8. Conduct security awareness and training for developers and system administrators to understand the risks associated with improper access controls and the importance of secure configuration.
