In `@Dockerfile`:
- Around line 3-6: The Dockerfile currently copies requirements.txt and the
project root but doesn't ensure the runtime data directory exists; because
app.py (starting near line 39) loads files from data/ at startup, add the data
directory into the image during build (e.g., update the Dockerfile to COPY the
repository data/ into the image or create an empty data/ and include required
files) so that when CMD runs gunicorn and app:app, app.py can find data/; modify
the Dockerfile around the existing COPY . . step to explicitly COPY data/ data/
(or create the directory and required fixtures) so no FileNotFoundError occurs
at startup.
In `@webapp/app.py`:
- Line 23: The app currently unconditionally applies ProxyFix via the statement
app.wsgi_app = ProxyFix(app.wsgi_app, x_proto=1, x_host=1), which trusts
X-Forwarded-* headers; change this so ProxyFix is only applied when an
environment flag (e.g., BEHIND_PROXY=true) is set or when running in a
production config: check the env/config before wrapping app.wsgi_app and leave
it unwrapped by default, update any related startup docs to require
BEHIND_PROXY=true when the app is behind a reverse proxy, and ensure the
conditional preserves the same ProxyFix parameters (x_proto=1, x_host=1) when
enabled.
- Line 10: The project imports ProxyFix from werkzeug in app.py but werkzeug is
not declared as a dependency; add werkzeug (version >=1.0) to your project's
dependency manifest (e.g., requirements.txt, setup.py install_requires, or
pyproject.toml [tool.poetry.dependencies] as appropriate) so the runtime can
install it, and run your dependency installer (pip install -r requirements.txt
or equivalent) to verify the app can import ProxyFix successfully.

Dockerfile requires data/ directory to be present for the app to start.
The requirements.txt is correctly configured with all necessary runtime dependencies (Flask, gunicorn, etc.). However, app.py attempts to load data files from data/ during startup (line 39 and beyond), and this directory is missing. The application will crash with a FileNotFoundError at runtime. Either add the data/ directory to the Docker image or copy it from the repository during the build.

Add werkzeug as a project dependency.
ProxyFix is imported on line 10, but werkzeug is not declared in any dependency file (requirements.txt, setup.py, pyproject.toml, etc.). The application will fail at runtime if werkzeug is not installed. Add it to your dependency declaration with a compatible version (1.0+).

Make ProxyFix configuration conditional or document reverse proxy requirement.
Enabling ProxyFix unconditionally means the app will trust X-Forwarded-* headers from any client. If the app is accidentally exposed without a reverse proxy (e.g., during development or misconfiguration), clients can forge these headers to:
- Bypass the HTTP→HTTPS redirect (line 352) by sending
X-Forwarded-Proto: https - Manipulate
request.urlandurl_for()results
🔒 Proposed fix: Make ProxyFix conditional on environment
+import os
+
app = Flask(__name__)
-app.wsgi_app = ProxyFix(app.wsgi_app, x_proto=1, x_host=1)
+# Only enable ProxyFix when behind a reverse proxy
+if os.environ.get('BEHIND_PROXY', 'false').lower() == 'true':
+ app.wsgi_app = ProxyFix(app.wsgi_app, x_proto=1, x_host=1)Then set BEHIND_PROXY=true in the production environment (Docker, systemd, etc.).
