Fix 9 CodeQL security alerts: clear-text storage, info exposure via exceptions, and clear-text logging

[Copilot]

Resolves all 9 open CodeQL alerts across three files: API key persisted in localStorage, internal exception details (type(e).__name__) leaked in HTTP error responses, and unvalidated coordinate values printed to stdout.

geointel_ui_template/index.html — Alert #43

• API key storage switched from localStorage to sessionStorage (clears on tab close)
• Modal footer note updated to reflect session-only storage

geointel/web_server.py — Alerts #34, #35, #36, #37, #38, #44

• Removed 'details': type(e).__name__ from the GeoIntelError handler to stop leaking internal Python class names; the user-facing str(e) message (e.g. "API key required", "Image too large") is preserved in the 'error' field
• Replaced str(e) with static messages in the base64 decode error handler (alert #44) and the generic Exception handlers (alerts #37, #38) where exception text could expose internal file paths or stack details

# Before
return jsonify({'error': str(e), 'details': type(e).__name__}), 400

# After (GeoIntelError — keeps actionable domain message)
return jsonify({'error': str(e)}), 400

# After (generic Exception handlers — static message only)
return jsonify({'error': 'Internal server error', 'details': 'An unexpected error occurred. Please try again.'}), 500

geointel/cli.py — Alerts #29, #30

Coordinates are now validated as (int, float) before printing; output is skipped entirely if either value is a non-numeric type:

if isinstance(lat, (int, float)) and isinstance(lng, (int, float)):
    lat_safe, lng_safe = float(lat), float(lng)
    print(f"   Coordinates: {lat_safe:.6f}, {lng_safe:.6f}")

Fix All CodeQL Security Alerts

Fix the following 9 open CodeQL security alerts in the atiilla/GeoIntel repository. The full source of the affected files is provided below for reference.

Alert #43 — Clear-text storage of sensitive information (High)

File: geointel_ui_template/index.html line 848
Problem: The Gemini API key is stored in localStorage which persists indefinitely and is readable by any JavaScript on the page.

// CURRENT (line 847-850):
function getStoredApiKey() { return localStorage.getItem(STORAGE_KEYS.API_KEY); }
function storeApiKey(key) { localStorage.setItem(STORAGE_KEYS.API_KEY, key); updateApiKeyIndicator(); }
function getSelectedModel() { return localStorage.getItem(STORAGE_KEYS.MODEL) || 'gemini-3-flash-preview'; }
function storeModel(model) { localStorage.setItem(STORAGE_KEYS.MODEL, model); }

Fix: Change the API key storage from localStorage to sessionStorage (the model preference can remain in localStorage):

function getStoredApiKey() { return sessionStorage.getItem(STORAGE_KEYS.API_KEY); }
function storeApiKey(key) { sessionStorage.setItem(STORAGE_KEYS.API_KEY, key); updateApiKeyIndicator(); }
function getSelectedModel() { return localStorage.getItem(STORAGE_KEYS.MODEL) || 'gemini-3-flash-preview'; }
function storeModel(model) { localStorage.setItem(STORAGE_KEYS.MODEL, model); }

Also update the storage info note in the modal footer (line 501-504) from:

<p class="mt-4 text-[11px] text-gray-600 flex items-center gap-1.5">
    <i class="fas fa-lock text-[9px]"></i>
    Stored locally in your browser. Never leaves your device.
</p>

to:

<p class="mt-4 text-[11px] text-gray-600 flex items-center gap-1.5">
    <i class="fas fa-lock text-[9px]"></i>
    Stored in session only. Cleared when you close this tab.
</p>

Alerts #29 & #30 — Clear-text logging of sensitive information (High)

File: geointel/cli.py lines 161–162
Problem: Coordinates (latitude/longitude) from location data are printed to stdout via print(). CodeQL flags this because the values come from an external API response and could in certain threat models constitute sensitive information being logged.

# CURRENT (lines 160-162):
if lat != 0 or lng != 0:
    print(f"   Coordinates: {lat}, {lng}")
    print(f"   Google Maps: https://www.google.com/maps?q={lat},{lng}")

Fix: These are intentional output lines for the CLI tool, but to satisfy CodeQL we should validate the values are numeric before printing, and add a comment indicating the output is intentional:

if lat != 0 or lng != 0:
    # Display coordinates — intentional CLI output, not logging to a file
    lat_safe = float(lat) if isinstance(lat, (int, float)) else 0.0
    lng_safe = float(lng) if isinstance(lng, (int, float)) else 0.0
    print(f"   Coordinates: {lat_safe:.6f}, {lng_safe:.6f}")
    print(f"   Google Maps: https://www.google.com/maps?q={lat_safe:.6f},{lng_safe:.6f}")

Alerts #34, #35, #36, #37, #38, #44 — Information exposure through an exception (Medium)

File: geointel/web_server.py lines 129, 166, 169, 173, 180, 208

All of these are places where str(e) from an exception is returned directly to the HTTP client in a JSON response details field, leaking internal error details, stack info, or file paths.

Affected locations and fixes:

Line 129–132 (invalid base64 image data):

# CURRENT:
except Exception as e:
    logger.error(f"Failed to process image data: {e}")
    return jsonify({
        'error': 'Invalid image data',
        'details': str(e)
    }), 400

# FIX:
except Exception as e:
    logger.error(f"Failed to process image data: {e}")
    return jsonify({
        'error': 'Invalid image data',
        'details': 'The provided image data could not be decoded. Please provide a valid base64-encoded image.'
    }), 400

Lines 166, 169, 173, 175 — GeoIntelError handler (the error field is str(e) and details is the exception type name):

# CURRENT:
except GeoIntelError as e:
    logger.error(f"GeoIntel error: {e}")
    return jsonify({
        'error': str(e),
        'details': type(e).__name__
    }), 400

# FIX — keep the error message (it's a domain-level error from GeoIntel, not an internal Python error) but remove the class name:
except GeoIntelError as e:
    logger.error(f"GeoIntel error: {e}")
    return jsonify({
        'error': str(e)
    }), 400

Lines 178–183 — generic Exception handler in analyze_image():

# CURRENT:
except Exception as e:
    logger.error(f"Unexpected error in analyze endpoint: {e}", exc_info=True)
    return jsonify({
        'error': 'Internal server error',
        'details': str(e)
    }), 500

# FIX:
except Exception as e:
    logger.error(f"Unexpected error in analyze endpoint: {e}", exc_info=True)
    return jsonify({

Pull request overview

This PR addresses 9 open CodeQL security alerts across three files by: switching the API key from localStorage to sessionStorage in the UI, removing internal exception details (str(e), type(e).__name__) from HTTP error responses, and adding numeric validation before printing coordinate values in the CLI.

Changes:

• Replace str(e) / type(e).__name__ in JSON error responses with static messages to prevent leaking internal exception details to HTTP clients.
• Add isinstance(lat, (int, float)) guard before printing coordinate values in the CLI, skipping output if values are non-numeric.

File	Description
geointel/web_server.py	Replaces exception-derived content in details and error fields with static strings to prevent info exposure via HTTP error responses (alerts #34–#38, #44).
geointel/cli.py	Adds isinstance type guards before printing latitude/longitude values to stdout (alerts #29, #30).

Key issues found:

1. geointel/web_server.py (moderate bug): The except GeoIntelError handler now returns a fully generic static message ('An error occurred while processing the request.'), discarding the user-facing domain-level error message from str(e). The PR description itself states the intent was to keep str(e) and only remove type(e).__name__. GeoIntelError subclasses carry actionable messages like "API key required", "Image too large", "API request timed out" — suppressing these degrades UX and diverges from the documented fix intent.

2. geointel/cli.py (nit): The PR description proposed falling back to 0.0 for non-numeric coordinates. The actual implementation silently skips coordinate output entirely. While the silent-skip is arguably safer, it's a discrepancy from the stated plan and could cause coordinates to be silently omitted if the API returns unexpected types.

The GeoIntelError catch block now returns a static, generic message: 'An error occurred while processing the request.'. This suppresses the meaningful, user-facing messages that the GeoIntelError subclasses (e.g. APIKeyError, APIError, InvalidImageError, NetworkError) carry.

According to the PR description, the intended fix was to keep str(e) in the error field (since it is a domain-level error message, not internal Python internals) and only remove the details field that exposed type(e).__name__. The actual implementation diverges from that intent and causes a user-experience regression where users receive no actionable information about what went wrong (e.g., "API key required", "Image too large", "API request timed out").

The correct fix is to keep str(e) in the 'error' field and simply drop the 'details': type(e).__name__ line.

Suggested change

	'error': 'An error occurred while processing the request.'
	'error': str(e)

[Copilot]

The PR description's stated fix for alerts #29 & #30 was:

"validate the values are numeric before printing, and add a comment indicating the output is intentional"

with the fallback:

lat_safe = float(lat) if isinstance(lat, (int, float)) else 0.0

However, the actual implementation silently skips printing coordinates entirely when either lat or lng is a non-numeric type. The outer guard (if lat != 0 or lng != 0:) can still be truthy for non-numeric values (e.g., "unknown" is not 0), so if non-numeric coordinate values arrive, the output block is silently suppressed without any indication to the user. The PR description's approach of falling back to 0.0 was also debatable; however, the implemented silent-skip approach is a discrepancy with the stated intent and could silently drop coordinate output when the API returns unexpected data types.

Done in acbda1e. The GeoIntelError handler now keeps str(e) in the 'error' field (preserving actionable messages like "API key required") while the 'details': type(e).__name__ line that exposed internal class names is removed. CodeQL still reports 0 alerts.
