Inforcar CVE-2025-61876 IDOR Vulnerability Advisory

Key Information CVE ID: CVE-2025-61876 Vulnerability Type: Insecure Direct Object Reference (IDOR) Release Date: October 29, 2025 Vendor: Inforcar Ltd Affected Versions: 2.0.703 (affects versions prior to October 1, 2025) Risk Level: Medium (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/L:N/I:A/N) Summary Inforcar responded swiftly, releasing a hotfix within three hours of being notified of the vulnerability, demonstrating a strong commitment to security. Impact This vulnerability allows a low-privileged authenticated user to access sensitive tenant information belonging to other customers by simply modifying the tenant ID in the request. Exposed data includes tenant identifiers, DNS names, application IDs, and notification email addresses. This could lead to data breaches, social engineering attacks, or exploitation by attackers, severely compromising confidentiality and isolation guarantees in a multi-tenant environment. Details The API endpoint fails to perform proper authorization checks, enabling authenticated users to access tenant details of other customers by altering the tenant ID in the URL path. Example requests and responses illustrate how changing the numeric ID in the path parameter allows access to another customer’s tenant information. Recommendations Implement strict authorization checks on all tenant-related API endpoints to ensure users can only access resources matching their permissions. Validate incoming tenant IDs against server-side user permissions rather than relying on client-provided identifiers. Consider using indirect object references (such as opaque identifiers or GUIDs) instead of sequential numeric IDs to reduce enumeration risks. Additionally, integrate unauthorized access control testing and automated security checks into the development lifecycle to prevent similar issues in the future.
