CVE-2026-93593

ArcadeDB before 26.9.1 TimeSeries ACL Bypass via Type Permission

CVSS 4.0 8.6 HIGHCVSS 3.1 8.1 HIGHCheck source for fixed versionsKEV status unknown
Original advisory

cve-program · CVE-2026-93593

Published

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.
