AI-suggested
Upgrade to ArcadeDB version 26.9.1 or later, where this authorization issue has been fixed. No other mitigation guidance is provided; applying the official fix is recommended.
Description
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.
