The exploit requires only network access to the Harbor UI and no special configuration or privilege escalation. The absence of a KEV listing does not reduce the risk, as the credentials are trivial to guess and the vulnerability is well documented. An attacker who gains administrative access can compromise the integrity and confidentiality of all container artifacts in the registry."}}}}, "created": "2026-03-24T10:33:43.050219+00:00", "updated": "2026-03-25T21:27:58.614356+00:00", "vendors": ["goharbor", "goharbor$PRODUCT$harbor"]}
