Hello @doomedraven, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

Summary of Changes

This pull request introduces reCAPTCHA verification to the CAPE Sandbox web application. It adds a middleware component that checks for reCAPTCHA responses on requests and verifies them. If the verification fails, an error page is rendered. The reCAPTCHA protection can be enabled or disabled via a configuration setting. The middleware is added to the Django middleware stack conditionally based on the configuration.

Highlights

• reCAPTCHA Middleware: Introduces a new middleware component, RecaptchaVerificationMiddleware, to handle reCAPTCHA verification for incoming requests.
• Configuration Setting: Adds a captcha_protected_analysis_view setting in web.conf.default to control whether reCAPTCHA protection is enabled.
• Conditional Middleware Inclusion: Modifies settings.py to conditionally include the RecaptchaVerificationMiddleware in the Django middleware stack based on the captcha_protected_analysis_view setting.

A bot's advance, a human's plight,
reCAPTCHA stands, a digital knight.
With twisted words and blurry scenes,
It guards the web from coded fiends.

Code Review

This pull request introduces a reCAPTCHA verification middleware to protect specific views in the CAPE Sandbox web interface. The changes involve adding a configuration option to enable/disable reCAPTCHA protection for the analysis view, implementing the middleware to verify reCAPTCHA responses, and integrating the middleware into the Django settings. Overall, the implementation seems reasonable, but there are a few areas that could be improved.

Summary of Findings

• Configuration option usage: The configuration option captcha_protected_analysis_view is added but not fully utilized. The middleware currently skips reCAPTCHA verification for /apiv2/ paths and has commented-out code for applying it to /analysis/. The configuration option should be used to dynamically enable/disable the reCAPTCHA protection for the analysis view.
• Error handling and logging: The error handling in the middleware is basic. It only prints a message to the console when reCAPTCHA verification fails. More robust error handling and logging mechanisms should be implemented, potentially including fail2ban integration as suggested in the TODO comment.
• Security considerations: The middleware currently applies reCAPTCHA to all POST requests. This might not be desirable, as some POST requests might not require reCAPTCHA protection. The middleware should be configured to only apply reCAPTCHA to specific views or requests that require it.

Merge Readiness

The pull request introduces a valuable security feature by adding reCAPTCHA verification. However, the current implementation has some limitations and potential issues that should be addressed before merging. Specifically, the configuration option usage, error handling, and security considerations need to be improved. I am unable to approve this pull request, and recommend that others review and approve this code before merging. At a minimum, the high severity issues should be addressed before merging.
