🚨 Severity: CRITICAL
💡 Vulnerability: The pgvector client was interpolating the configured table name directly into SQL queries using fmt.Sprintf. While this comes from configuration, it presents a SQL injection risk if the configuration is dynamically populated or manipulated.
🎯 Impact: An attacker could execute arbitrary SQL commands if they could control the PGVECTOR_TABLE environment variable.
🔧 Fix: Added strict regex validation (^[a-zA-Z0-9_.]+$) during client initialization to ensure the table name only contains valid characters for SQL identifiers.
✅ Verification: Handled via local test suites (go test ./...) and compilation checks (go build ./...).
