CVE-2026-82266

Estado: AplazadaCrítica (9.3)—

Redpanda through 26.2.2 binds the Admin API to 0.0.0.0:9644 with admin_api_require_auth defaulting to false, treating unauthenticated requests as superusers. Attackers can reach port 9644 without credentials to create and delete broker accounts, modify cluster configuration, and disrupt partition replication.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
