BREW-glances-CVE-2026-32611 — Glances has a SQL Injection in DuckDB Export via Unparameterized DDL Statements

Affected: Homebrew: glances

Glances is an open-source system cross-platform monitoring tool. The GHSA-x46r fix (commit 39161f0) addressed SQL injection in the TimescaleDB export module by converting all SQL operations to use parameterized queries and `psycopg.sql` composable objects. However, the DuckDB export module (`glances/exports/glances_duckdb/__init__.py`) was not included in this fix and contains the same class of vulnerability: table names and column names derived from monitoring statistics are directly interpolated into SQL statements via f-strings. While DuckDB INSERT values already use parameterized queries (`?` placeholders), the DDL construction and table name references do not escape or parameterize identifier names. Version 4.5.3 provides a more complete fix.

## Summary

The GHSA-x46r fix (commit 39161f0) addressed SQL injection in the TimescaleDB export module by converting all SQL operations to use parameterized queries and `psycopg.sql` composable objects. However, the DuckDB export module (`glances/exports/glances_duckdb/__init__.py`) was not included in this fix and contains the same class of vulnerability: table names and column names derived from monitoring statistics are directly interpolated into SQL statements via f-strings. While DuckDB INSERT values already use parameterized queries (`?` placeholders), the DDL construction and table name references do not escape or parameterize identifier names.

## Details

The DuckDB export module constructs SQL DDL statements by directly interpolating stat field names and plugin names into f-strings.

**Vulnerable CREATE TABLE construction** (`glances/exports/glances_duckdb/__init__.py:156-162`):

```python create_query = f""" CREATE TABLE {plugin} ( {', '.join(creation_list)} );""" self.client.execute(create_query) ```

The `creation_list` is built from stat dictionary keys in the `update()` method (`glances/exports/glances_duckdb/__init__.py:117-118`):

```python for key, value in plugin_stats.items(): creation_list.append(f"{key} {convert_types[type(self.normalize(value)).__name__]}") ```

The INSERT statement also uses the unescaped `plugin` name (`glances/exports/glances_duckdb/__init__.py:172-174`):

```python insert_query = f""" INSERT INTO {plugin} VALUES ( {', '.join([…
