CVE-2025-61876 is a medium-severity vulnerability classified as an Insecure Direct Object Reference (IDOR) affecting the Inforcer Platform version 2.0.153. The vulnerability exists in the /tenants/{id} API endpoint, where the platform fails to properly enforce access control on tenant identifiers. An authenticated user with low privileges can manipulate the tenant ID parameter in the API request URL to enumerate and access tenant data belonging to other clients. This flaw arises from insufficient authorization checks, allowing unauthorized data disclosure. The vulnerability impacts confidentiality but does not affect data integrity or system availability. Exploitation requires authentication but no user interaction, and the attack vector is network-based, making it feasible for internal or external attackers with valid credentials. Although no public exploits have been reported, the vulnerability poses a risk to multi-tenant environments where sensitive tenant information could be exposed. The CWE-639 classification highlights the root cause as improper authorization in direct object references. The lack of available patches necessitates immediate attention to access control mechanisms within the affected API endpoint.

For European organizations using the Inforcer Platform, this vulnerability could lead to unauthorized disclosure of tenant-specific information, potentially exposing sensitive client data and violating data protection regulations such as GDPR. The confidentiality breach could undermine client trust and lead to legal and reputational consequences. Since the vulnerability does not affect integrity or availability, operational disruption is unlikely. However, the ability for low-privilege users to access other tenants' data increases the risk of insider threats and lateral movement within the platform. Organizations operating in regulated sectors like finance, healthcare, or government are particularly at risk due to the sensitivity of tenant data. The multi-tenant nature of the platform amplifies the impact, as a single compromised account could expose multiple clients' information. This vulnerability also raises compliance concerns under European data privacy laws, potentially resulting in fines or sanctions if exploited.

European organizations should implement strict access control validation on the /tenants/{id} API endpoint to ensure users can only access tenant data they are authorized for. This includes enforcing tenant ID authorization checks server-side, independent of client-supplied parameters. Conduct a thorough code review and penetration testing focused on IDOR vulnerabilities across all API endpoints. Employ robust authentication and authorization frameworks, such as role-based access control (RBAC) or attribute-based access control (ABAC), to limit user privileges appropriately. Monitor API logs for unusual access patterns or repeated tenant ID enumeration attempts to detect potential exploitation. If possible, implement rate limiting and anomaly detection on API requests. Organizations should also engage with the Inforcer Platform vendor for patches or updates and apply them promptly once available. In the interim, restrict access to the API to trusted networks or VPNs and educate users about the risks of credential sharing. Finally, ensure incident response plans include procedures for handling data exposure incidents related to this vulnerability.
