IDOR Vulnerability in Chiline Cloud

Chiline Cloud, developed by Inventec Appliances, is susceptible to an Insecure Direct Object Reference (IDOR) vulnerability, tracked as CVE-2026-19424. This vulnerability enables unauthenticated remote attackers to manipulate specific URL or API parameters to bypass authorization controls. By changing these identifiers, an attacker can access sensitive user data residing in the application. This issue poses a significant risk to data confidentiality, as it requires no prior authentication to execute. Security operations teams should identify any traffic targeting the Chiline Cloud API interfaces and evaluate the application logs for unauthorized parameter manipulation attempts where user-specific identifiers are cycled or altered in sequence.

Impact

Successful exploitation allows unauthenticated attackers to perform unauthorized data exfiltration by reading sensitive information from other users' accounts. The vulnerability, which carries a CVSS v3.1 base score of 7.5, presents a high risk of privacy breaches and regulatory non-compliance for organizations utilizing Chiline Cloud for data storage or management.

Recommendation

• Audit web server and API gateway logs for sequential or suspicious variations in object ID parameters (e.g., user IDs, account numbers) in GET requests.
• Patch the Chiline Cloud instance immediately upon the release of a security update from Inventec Appliances addressing CVE-2026-19424.
• Implement strict object-level access control checks within the application code to ensure that the requester has valid authorization for the specific object identifier being accessed.
