CVE-2025-62966 is a missing authorization vulnerability found in Apiki's GoCache product, specifically affecting versions up to and including 1.3.6. The root cause is an incorrectly configured access control mechanism that fails to properly enforce authorization checks on certain operations or resources within the GoCache CDN platform. This allows an attacker with limited privileges (PR:L) to perform unauthorized actions remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality and integrity (C:L/I:L) but does not affect availability (A:N). Since GoCache is a content delivery network caching solution, unauthorized access could lead to exposure or modification of cached content or configuration data, potentially undermining the security and trustworthiness of the CDN service. The CVSS score of 5.4 reflects a medium severity level, indicating moderate risk. No public exploits have been reported yet, but the vulnerability is published and should be addressed proactively. The lack of patch links suggests that a fix may still be pending or that users must apply configuration changes to mitigate the issue. The vulnerability highlights the importance of correctly implementing and validating access control policies in CDN and caching platforms to prevent privilege escalation or unauthorized data access.

For European organizations, this vulnerability poses a risk to the confidentiality and integrity of data served or cached via Apiki GoCache. Unauthorized access could lead to leakage of sensitive information or unauthorized modification of cached content, which may affect customer trust and compliance with data protection regulations such as GDPR. Organizations relying on GoCache for content delivery, especially those handling personal or sensitive data, could face reputational damage and potential regulatory penalties if exploited. The medium severity rating indicates that while the risk is not critical, it is significant enough to warrant timely remediation. The vulnerability could also be leveraged as a stepping stone for further attacks within the network if attackers gain foothold through this flaw. Given the remote exploitability and lack of user interaction requirement, the attack surface is broad, increasing the likelihood of exploitation if left unmitigated.

European organizations should immediately review and tighten access control configurations within their GoCache deployments to ensure authorization checks are correctly enforced. Until an official patch is released, administrators should restrict access to management interfaces and sensitive resources to trusted IP ranges and authenticated users only. Implement network segmentation to isolate CDN management components from general network access. Monitor logs and network traffic for unusual access patterns or unauthorized attempts to access restricted resources. Engage with Apiki support or vendor channels to obtain patches or recommended configuration updates as soon as they become available. Additionally, conduct regular security audits and penetration tests focused on access control mechanisms within CDN infrastructure. Employ web application firewalls (WAFs) or similar security controls to detect and block suspicious requests targeting GoCache endpoints. Finally, ensure incident response plans include scenarios involving CDN compromise to enable rapid containment and recovery.
