Implements critical OAuth 2.0 security improvements to protect against authorization code interception attacks and improve provider compatibility: - Add PKCE (RFC 7636) support with SHA-256 code challenge/verifier - Fix access token extraction to use standard field instead of Extra() - Add OAuth error parameter handling (access_denied, invalid_scope, etc.) - Maintain backward compatibility for non-PKCE flows This brings the OAuth implementation up to modern security standards as recommended by Auth0, Okta, and the OAuth 2.0 Security Best Current Practice (RFC 8252). Backend changes: - Add code_verifier parameter to ExchangeToken with PKCE support - Use token.AccessToken for better provider compatibility - Update proto definition with optional code_verifier field Frontend changes: - Generate cryptographically secure PKCE parameters - Include code_challenge in authorization requests - Handle and display OAuth provider errors gracefully - Pass code_verifier during token exchange 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |
