Implement Cloudflare Zero Trust (Access) as an authentication provider, enabling users authenticated via Cloudflare to access Metabase without a second login step. Features: - JWT validation using RS256 with Cloudflare's JWKS endpoint - JIT user provisioning (auto-create users on first login) - Optional require-auth mode to enforce Cloudflare-only access - Allowlisted paths for health checks and setup endpoints Security measures: - RS256-only algorithm allowlist (prevents alg=none attacks) - SSRF protection for JWKS URL validation - JWKS caching with automatic refresh on key rotation - Deactivated user rejection - Email normalization before user lookup - Audit event logging Configuration via environment variables: - MB_CLOUDFLARE_ZERO_TRUST_ENABLED - MB_CLOUDFLARE_ZERO_TRUST_TEAM_NAME - MB_CLOUDFLARE_ZERO_TRUST_AUDIENCE_TAG - MB_CLOUDFLARE_ZERO_TRUST_USER_PROVISIONING_ENABLED - MB_CLOUDFLARE_ZERO_TRUST_REQUIRE_AUTH - MB_CLOUDFLARE_ZERO_TRUST_ALLOWED_PATHS Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Fix Base64 URL decoder usage in JWT header decoding - Use with-redefs instead of with-temporary-setting-values in middleware tests - Use correct metabase.test namespace in test files Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add derive statements to register Cloudflare Zero Trust events with the Metabase event system. Events must derive from :metabase/event for publish-event! to work. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Allow disabling password login without requiring a premium license. This enables the MB_ENABLE_PASSWORD_LOGIN=false environment variable to work in the open source build. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
