Published: 14 January 2023
Summary
CVE-2023-22478 is a high-severity Missing Authorization (CWE-862) vulnerability in Fit2Cloud Kubepi. Its CVSS base score is 7.3 (High).
Operationally, ranked in the top 0.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
KubePi, an open-source Kubernetes management panel, contains a missing authorization vulnerability (CWE-862) in its API. Unauthenticated network callers can reach endpoints that were intended to be protected, resulting in leakage of sensitive information along with limited integrity and availability impacts. The flaw affects all versions prior to the 1.6.4 release and carries a CVSS 3.1 base score of 7.3.
An attacker with no credentials and only network reachability to a KubePi instance can directly invoke the affected API interfaces. Successful exploitation yields disclosure of sensitive cluster or application data and may permit limited state-changing operations, all without user interaction or elevated privileges.
The project’s security advisory and release notes state that the issue is resolved in version 1.6.4; the corresponding fix is tracked in commit 0c6774bf5d9003ae4d60257a3f207c131ff4a6d6. No workarounds are documented. The associated EPSS score remains elevated, with a current value of 0.8112 and a recorded peak of 0.8367.

Mitigating Controls
Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
