The fix for CVE-2026-47735 (released 2026.06.1) is incomplete. It added a DuckDB sandbox (SET GLOBAL allowed_directories=[ ]; SET GLOBAL enable_external_access=false) and an Arc SQL-layer denylist of the literal functions read_parquet( and arc_partition_agg(. The sandbox correctly blocks reads outside the storage root (OS files, http:// SSRF), but it allowlists the entire multi-tenant storage root, and the SQL denylist still misses the rest of the DuckDB I/O family the original advisory enumerated. …
