fix: add path validation in updater.py

[anupamme]

Summary

Fix critical severity security issue in updater.py.

Vulnerability

Field	Value
ID	V-002
Severity	CRITICAL
Scanner	multi_agent_ai
Rule	V-002
File	updater.py:69
Assessment	Likely exploitable
CWE	CWE-22

Description: The script reads CSV file content and uses the first row as a Jinja2 template. The query string from the CSV file is passed directly to jinja2.Environment.from_string() and rendered without sandboxing. If an attacker can control the CSV file content (achievable via V-001 path traversal), they can inject malicious Jinja2 expressions to execute arbitrary Python code.

Evidence

Exploitation scenario: Step 1: Use path traversal to access a writable location or create a malicious CSV file.

Scanner confirmation: multi_agent_ai rule V-002 flagged this pattern.

Production code: This file is in the production codebase, not test-only code.

Threat Model Context

This is a Python library - vulnerabilities affect applications that import this code.

Changes

• updater.py

Behavior Preservation

The change is scoped to 1 file on the vulnerable path; it only tightens handling of untrusted input and leaves valid inputs unaffected.
