HIGHPre-NVD 7.17.1—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 78% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

Arc is an open, SQL-native time-series database for telemetry. Prior to version 26.06.1, Arc's user-SQL validator (internal/api/query.go:ValidateSQLRequest) blocked only read_parquet( and arc_partition_agg( via regex denylist. The broader DuckDB I/O function family — read_csv_auto, read_csv, read_json, read_json_auto, read_text, read_blob, glob, parquet_metadata, parquet_schema, read_xlsx, etc. — was not blocked. RBAC table-reference extraction inspected only FROM/JOIN clauses, so scalar table functions in the SELECT list slipped past both layers. This is fixed in 2026.06.1 via a structural sandbox at the DuckDB layer. After lockdown, DuckDB refuses to open any file outside the allowlist and refuses further INSTALL/LOAD. Already-loaded extensions remain callable. Some workarounds are available. Restrict API access to known-trusted networks via firewall rules or, as a temporary mitigation, add read_csv*/read_json*/glob etc. to dangerousSQLPattern in internal/api/query.go.
