CVE-2026-3053 identifies a security vulnerability in the DataLinkDC dinky software, specifically in versions 1.2.0 through 1.2.5. The issue resides in the addInterceptors function within the dinky-admin/src/main/java/org/dinky/configure/AppConfig.java file, which is part of the OpenAPI endpoint component. This function lacks proper authentication controls, allowing remote attackers to bypass authentication mechanisms entirely. The vulnerability enables attackers to perform unauthorized manipulations remotely without requiring any privileges or user interaction. The absence of authentication in this critical function can lead to unauthorized access, potentially allowing attackers to execute arbitrary commands, modify configurations, or access sensitive data. The vendor was informed early but has not provided a patch or mitigation guidance, increasing the urgency for users to implement alternative protective measures. The CVSS 4.0 base score of 6.9 indicates a medium severity level, with the attack vector being network-based, no required privileges, and no user interaction needed. The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as indicated by the CVSS vector. Although no known exploits are currently active in the wild, the public disclosure of the vulnerability and the lack of vendor response elevate the risk of exploitation by threat actors. Organizations relying on dinky for their data integration or management workflows should assess their exposure and apply compensating controls promptly.

The vulnerability allows remote attackers to bypass authentication controls, potentially leading to unauthorized access to administrative functions within the dinky application. This can result in unauthorized data access, modification of system configurations, or disruption of services, impacting confidentiality, integrity, and availability. Organizations using affected versions may face risks including data breaches, system compromise, and operational disruptions. Since the vulnerability requires no authentication or user interaction, exploitation can be automated and scaled, increasing the risk of widespread attacks. The lack of vendor response and patches means organizations must rely on internal mitigations, increasing operational burden. Critical infrastructure or enterprises using dinky for data processing or integration are particularly at risk, as attackers could leverage this vulnerability to pivot into broader network environments or exfiltrate sensitive information. The medium severity rating reflects moderate impact potential but high exploitability, making timely mitigation essential to prevent escalation.

1. Immediately audit all instances of DataLinkDC dinky to identify affected versions (1.2.0 through 1.2.5). 2. Restrict network access to the dinky-admin OpenAPI endpoint by implementing strict firewall rules or network segmentation to limit exposure only to trusted management networks. 3. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized requests targeting the addInterceptors function or suspicious API calls. 4. Implement strong authentication and authorization proxies in front of the dinky admin interface to enforce access control externally until a vendor patch is available. 5. Monitor logs and network traffic for unusual or unauthorized access attempts to the OpenAPI endpoints. 6. Consider upgrading to a future patched version once released or applying vendor-recommended fixes if available. 7. If feasible, temporarily disable or isolate the vulnerable OpenAPI endpoint functionality to prevent exploitation. 8. Educate security teams about this vulnerability and prepare incident response plans for potential exploitation scenarios. 9. Engage with the vendor or community forums for updates or unofficial patches. 10. Conduct penetration testing to verify the effectiveness of implemented mitigations.
