Walkthrough

The Content Security Policy (CSP) configuration was updated across multiple modules to include a new worker_src directive. This directive allows web workers to be loaded from the same origin ('self') and from blob URLs ("blob:"). No other logic, error handling, or control flow was changed in any of the affected files, and there were no alterations to public or exported entities.

Changes

Files	Change Summary
kairon/actions/server.py kairon/api/app/main.py kairon/chat/server.py	Updated CSP configuration to add worker_src directive for 'self' and "blob:" sources.
kairon/async_callback/main.py kairon/evaluator/main.py kairon/events/server.py kairon/history/main.py	Extended CSP configuration with .worker_src("'self'", "blob:") to permit web workers from same origin and blob URLs.

Poem

In the warren of code, a policy grew,
Now workers may hop from blob URLs too!
With 'self' and with "blob:", the rules are precise,
Security’s tight, but the workers play nice.
So here’s to the CSP, updated anew—
A safer, hoppier world for all code to pursue!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

kairon/events/server.py (1)

35-35: Content Security Policy updated to support web workers.

Added worker_src directive to allow loading web workers from the same origin and blob URLs, which is necessary for proper operation of web workers in modern browsers.

kairon/history/main.py (1)

38-38: Content Security Policy enhanced for web worker support.

Added worker_src directive with appropriate sources ('self' and "blob:") to enable proper web worker functionality.

kairon/chat/server.py (1)

50-50: Web worker security configuration added.

The CSP configuration has been properly updated to include the worker_src directive, maintaining consistent security policies across the application.

kairon/api/app/main.py (1)

47-47: Added web worker source directive to CSP.

This change aligns the CSP configuration with modern security best practices by explicitly defining allowed sources for web workers.

kairon/actions/server.py (1)

The addition of worker_src directive completes the consistent implementation of web worker support across all server modules.

kairon/evaluator/main.py (1)

28-28: Approve CSP worker-src directive addition
The addition of .worker_src("'self'", "blob:") correctly extends the allowed sources for web workers in the FastAPI secure headers.

🛠️ Refactor suggestion

Ensure CSP builder and manual config are in sync with worker-src
The worker_src("'self'", "blob:") directive was added to the CSP builder chain, but the csp_config used by generate_csp_header lacks a corresponding "worker-src" entry. Add "worker-src": ["'self'", "blob:"] to csp_config to maintain consistency.
