Budibase is a low code platform for creating internal tools, workflows, and admin panels. In 3.23.22 and earlier, the PostgreSQL integration constructs shell commands using user-controlled configuration values (database name, host, password, etc.) without proper sanitization. The password and other connection parameters are directly interpolated into a shell command. This affects packages/server/src/integrations/postgres.ts.

Affected: npm: @budibase/server

**Location**: `packages/server/src/integrations/postgres.ts:529-531`

#### Description The PostgreSQL integration constructs shell commands using user-controlled configuration values (database name, host, password, etc.) without proper sanitization. The password and other connection parameters are directly interpolated into a shell command.

#### Code Reference ```529:531:packages/server/src/integrations/postgres.ts const dumpCommand = `PGPASSWORD="${ this.config.password }" pg_dump --schema-only "${dumpCommandParts.join(" ")}"` ```

#### Attack Vector An attacker who can control database configuration values (e.g., through compromised credentials or configuration injection) can inject shell commands. For example: - Password: `password"; malicious-command; echo "` - Database name: `db"; rm -rf /; echo "`

#### Impact - Remote code execution - System compromise - Data exfiltration

#### Recommendation 1. Use environment variables for sensitive values instead of command-line arguments 2. Validate and sanitize all configuration values 3. Use proper escaping for shell arguments 4. Consider using a PostgreSQL library's native dump functionality instead of shell commands

#### Example Fix ```typescript import { execFile } from "child_process" import { promisify } from "util" const execFileAsync = promisify(execFile)

// Use execFile with proper argument handling const env = { ...process.env, PGPASSWORD: this.config.password }

const args = [ "--schema-only",…
