Operationally, ranked in the top 0.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2022-46463 is an access-control vulnerability affecting Harbor container registry versions 1.x through 2.5.3. The flaw, categorized under CWE-306, permits unauthenticated network access to both public and private image repositories, resulting in a CVSS 3.1 score of 7.5 with full confidentiality impact and no authentication or user interaction required.
Remote attackers can exploit the issue over the network to retrieve container images without credentials. The vendor maintains that the behavior matches documented configuration options and therefore does not constitute a defect requiring remediation.
Public references consist primarily of GitHub repositories that appear to contain discussion or proof-of-concept material. No official patch or mitigation guidance is provided in the available references. The associated EPSS score stands at 0.8008, indicating substantial exploitation interest.

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.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
