  "title": "TimeSeries ACL enforcement bypass in ArcadeDB Server",
  "summary": "ArcadeDB Server versions before 26.9.1 may not enforce security-group type ACLs for TimeSeries types. An authenticated user assigned a restricted group can read or insert TimeSeries samples despite explicit deny rules; exposure requires TimeSeries data protected through these type ACL entries.",
  "mitigation": "Upgrade com.arcadedb:arcadedb-server to version 26.9.1 or later. Until upgraded, restrict access to ArcadeDB instances and avoid relying on security-group `types` ACLs to protect TimeSeries data.",
