EPSS data is currently unavailable, and the vulnerability is not listed in the CISA KEV catalog. The likely attack vector requires an attacker to already be a trusted, elevated user within the system; once that condition is met, they can exploit the bug by creating rogue credentials to rotate or elevate access levels. Given the high severity and the need for privileged access, organizations with Esri Portal for ArcGIS deployments should treat this as an urgent exposure."}}}}, "created": "2026-04-22T02:15:05.406159+00:00", "updated": "2026-04-22T02:15:05.406170+00:00", "vendors": []}
