CVE-2025-13063 identifies a missing authorization vulnerability in DinukaNavaratna Dee Store version 1.0. The flaw resides in an unspecified function affecting multiple endpoints, allowing remote attackers to bypass authorization controls entirely. The vulnerability requires no authentication or user interaction, making it trivially exploitable over the network. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates that the attack can be performed remotely with low complexity and no privileges or user interaction, impacting confidentiality, integrity, and availability to a limited extent. The lack of authorization checks means attackers can potentially access or manipulate resources or data they should not have permission for, leading to unauthorized data exposure, modification, or disruption of service. Although the exact affected functions are unspecified, the mention of multiple endpoints suggests a systemic issue in the authorization logic. No patches or vendor advisories are currently available, and no exploits have been observed in the wild, but the exploit code has been published, increasing the risk of exploitation. This vulnerability highlights a critical security design flaw in the Dee Store application, emphasizing the need for rigorous access control validation in web applications.

For European organizations using DinukaNavaratna Dee Store 1.0, this vulnerability poses a significant risk of unauthorized access and manipulation of sensitive data or business logic. The missing authorization can lead to data breaches, unauthorized transactions, or service disruptions, impacting customer trust and regulatory compliance, especially under GDPR. Retailers and e-commerce platforms relying on Dee Store may face financial losses, reputational damage, and potential legal consequences if exploited. The medium severity score reflects that while the impact on confidentiality, integrity, and availability is limited, the ease of exploitation and lack of required privileges make it a practical threat. Organizations with exposed Dee Store endpoints on public networks are particularly vulnerable. The absence of known exploits in the wild currently limits immediate risk, but published exploit code increases the likelihood of future attacks. Overall, the vulnerability could facilitate lateral movement or privilege escalation within affected environments if combined with other weaknesses.

1. Immediately restrict network access to Dee Store 1.0 endpoints using firewalls or network segmentation to limit exposure to untrusted networks. 2. Implement compensating authorization controls at the application or web server level, such as reverse proxies enforcing access policies. 3. Conduct a thorough code review and security audit of the Dee Store authorization logic to identify and remediate missing checks. 4. Monitor logs and network traffic for unusual or unauthorized access patterns targeting Dee Store endpoints. 5. Engage with the vendor or development team to obtain or request patches addressing the missing authorization flaw. 6. If patching is not immediately possible, consider deploying Web Application Firewalls (WAFs) with custom rules to block exploit attempts. 7. Educate internal teams about the vulnerability and ensure incident response plans include scenarios involving unauthorized access to Dee Store. 8. Regularly update and harden the hosting environment to reduce the attack surface and prevent exploitation of chained vulnerabilities.
