CVE-2026-93593

Estado: AplazadaAlta (8.6)—

ArcadeDB before 26.9.1 fails to enforce security-group types ACL entries for TimeSeries types because the ACL resolver builds permissions from bucket IDs, but TimeSeries types do not own normal record buckets. An authenticated low-privilege user can read or insert TimeSeries samples despite explicit deny rules by exploiting the missing type-name-based access check that causes permission lookups to fail open.

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).

🎯 Técnicas ATT&CK
