The EPSS score is unavailable, and the vulnerability is not listed in the CISA KEV catalog, implying limited public exploitation data but a substantial risk to organizations that rely on strict team isolation."}}}}, "created": "2026-03-27T20:27:43.210699+00:00", "updated": "2026-03-27T20:27:43.210821+00:00", "vendors": []}
