CVE-2025-47558 is a high-severity vulnerability classified under CWE-862 (Missing Authorization) affecting the MapSVG product developed by PT Norther Lights Production. This vulnerability arises from insufficient access control mechanisms, allowing unauthorized users to access functionality that should be restricted by Access Control Lists (ACLs). Specifically, the flaw enables an attacker to invoke certain functions or access resources without proper authorization checks. The CVSS 3.1 base score of 7.5 reflects a high impact primarily on confidentiality, with no requirements for privileges or user interaction, and the vulnerability is exploitable remotely over the network. The vulnerability affects versions prior to 8.6.13, although the exact affected versions are not fully enumerated. The absence of known exploits in the wild suggests it is either newly discovered or not yet weaponized. The vulnerability does not impact integrity or availability but allows unauthorized disclosure of sensitive information or data accessible through the MapSVG application. MapSVG is a tool used to create interactive vector maps and visualizations, often integrated into web applications and dashboards, which may contain sensitive geographic or production data. The missing authorization could allow attackers to bypass intended restrictions and access confidential map data or administrative functions, potentially leading to data leakage or reconnaissance for further attacks.

For European organizations, the impact of CVE-2025-47558 can be significant depending on the deployment of MapSVG within their infrastructure. Organizations using MapSVG for internal or customer-facing applications that handle sensitive geographic, production, or operational data could face unauthorized data exposure. This could lead to breaches of confidentiality, regulatory non-compliance (e.g., GDPR), and reputational damage. Since the vulnerability does not require authentication or user interaction, attackers can exploit it remotely, increasing the risk of widespread unauthorized access. Sectors such as manufacturing, logistics, utilities, and government agencies that rely on detailed production or geographic mapping tools are particularly at risk. The exposure of sensitive operational data could also aid adversaries in planning further attacks or industrial espionage. Although no integrity or availability impact is noted, the confidentiality breach alone can have severe consequences, including legal penalties and loss of customer trust.

To mitigate CVE-2025-47558, European organizations should prioritize the following actions: 1) Immediately update MapSVG to version 8.6.13 or later where the authorization checks have been properly implemented. 2) Conduct an audit of all MapSVG instances to identify any unauthorized access or suspicious activity prior to patching. 3) Implement network-level access controls such as IP whitelisting or VPN requirements to restrict access to MapSVG administrative interfaces. 4) Employ Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized function calls or anomalous requests targeting MapSVG endpoints. 5) Review and tighten ACL configurations within the application and underlying infrastructure to ensure least privilege principles are enforced. 6) Monitor logs for unusual access patterns or data exfiltration attempts related to MapSVG. 7) If immediate patching is not feasible, consider temporarily disabling or isolating vulnerable MapSVG functionalities until a fix can be applied. 8) Educate development and operations teams about the importance of authorization checks in web applications to prevent similar issues in the future.
