Release 1.0.7

[prakhar-singh1928]

[1.0.7] - 2026-08-04 - Security Hardening, Unified Search, OAuth Improvements, Dataplane Enhancements, and Operational Reliability

Overview

Release 1.0.7 consolidates 57 PRs focused on security hardening, unified search and catalog APIs, OAuth and CSRF improvements, dataplane publishing, CPEX control-execution telemetry, MCP Apps compatibility, and CI/operational reliability:

• Security - Root URI policy hardening, token-scope enforcement, safer admin demotion, A2A authorization, REST outbound validation, CSRF response correctness, and patched container dependencies.
• API & Platform - Added v1 catalog and unified search endpoints, bulk team member creation, popup-based OAuth authorization, GatewayRead counts, and improved OAuth resource handling.
• Dataplane & MCP - Added per-backend header publication, opaque dataplane subject IDs, session-token identity resolution, and deprecated MCP Apps metadata compatibility.
• Observability & Plugins - Added CPEX control-execution telemetry and improved upstream MCP session diagnostics; replaced the in-tree SQL sanitizer with the maintained CPEX plugin.
• Operations - Improved Redis session recovery and connection handling, health-check recovery, s390x builds, production smoke checks, dependency security, and developer tooling.

Breaking Changes

• Unconditional weak-secret rejection - JWT_SECRET_KEY placeholder and known-weak values now cause SecurityConfigurationError at startup in every environment, including development. The __REPLACE_ME__ placeholder value is always rejected and will block startup. Update the JWT_SECRET_KEY manually to a strong secret (length > 32).

• Root URI policy now defaults to deny (internal#294) - Set ROOT_ALLOWED_SCHEMES before restart for every network scheme used by DEFAULT_ROOTS or new root registrations. file:// roots additionally require ROOT_ALLOW_FILE_SCHEME=true and non-empty ROOT_ALLOWED_FILE_PREFIXES. Invalid DEFAULT_ROOTS abort gateway startup; configure policy before upgrading, not after.

  • Root management API payloads are strict - POST /roots rejects unknown fields. PUT /roots/{root_uri} accepts only optional name; existing full-root PUT payloads containing uri, _meta, or custom fields now return HTTP 422.
  • Root-inclusive exports require unrestricted platform administration - Unfiltered export includes roots and returns HTTP 403 for team-scoped administrators. Run backup exports with unrestricted platform-admin credentials, or explicitly exclude roots when a scoped export is intended.
  • Root registrations are runtime state - Roots are held in memory and are not database-persisted. Manual registrations do not survive process restart; configure DEFAULT_ROOTS together with matching root policy when persistent startup roots are required.

• OAuth DCR endpoints now enforce un-narrowed admin scope (internal#460) - GET /oauth/registered-clients, GET /oauth/registered-clients/{gateway_id}, and DELETE /oauth/registered-clients/{client_id} now reject narrowed and public-only admin tokens with 403 Forbidden.

Security

• Fixed SSRF vulnerability in url_to_markdown_server MCP server (CWE-918), including DNS-rebinding protection through connection pinning and configurable allowlisting.
• API token scope enforcement (#4737) - Enforced scope-based access control for API tokens.
• Search Token Scoping (#5668) - Applied token-scoped team filtering to unified search results for administrators.
• Safe admin demotion (#5644) - Enforced safe rules when demoting administrators.
• A2A admin edit authorization (#5922) - Hardened authorization for A2A administrative edits.
• REST outbound validation (#5925) - Hardened validation of outbound REST tool requests.
• Patched libpq dependency (#5809) - Bumped UBI_MINIMAL to include the patched libpq.

Added

API & Platform

• v1 Catalog API (#5544) - Added the v1 catalog API.
• Unified Search API (#5610) - Added versioned GET /v1/search unified search endpoint.
• Bulk Team Member Creation (#5626) - Added bulk member creation support to TeamCreateRequest.
• Popup-Based OAuth Authorization (#5661) - Added popup authorization support with CSP-nonce'd postMessage responses for success and error paths.
• Gateway Counts (#5657) - Added prompt and resource counts to GatewayRead.

Dataplane & Observability

• Per-Backend Header Publication (#5924) - Published per-backend add_headers and remove_headers configuration.
• CPEX Control-Execution Telemetry (#6003) - Added structured per-plugin enforcement observability on tool invocations. Requires CPEX >= 0.1.2 and is a silent no-op on older builds. Added cpex.control.summary and cpex.control.result spans, configurable result flattening and limits, attribute policies, and optional reason and agent-id emission.
• Upstream MCP Session Diagnostics (#5631) - Improved diagnostics for upstream MCP session errors.

Removed

• lint-install-hooks, lint-pre-commit, lint-pre-push Make targets - Removed with the legacy lint-staged hook scripts. Remediation: remove stale .git/hooks/pre-commit and .git/hooks/pre-push, then run make configure-git.
• Granian HTTP server option (#5607) - Removed the Granian server option.
• Obsolete Redis fallback references (#5645) - Removed obsolete redis_fallback configuration references.

Changed

Auth, OAuth & Transport

• OAuth Resource UI and Origin Handling (#4476) - Added the OAuth Resource UI field, origin fallback, and softened auto-derived validation.
• Authorization-Code OAuth Reliability (#5244) - Resolved offline issues for authorization-code OAuth gateways.
• Session-Token Identity Resolution (#5802) - Resolved session-token subject UUIDs to email in streamable HTTP authentication.
• LLM Chat Session Resume (#5790) - Allowed any worker to resume LLM Chat sessions from Redis.
• MCP Apps Metadata Compatibility (#5764) - Honoured deprecated flat ui/resourceUri metadata.

Dataplane, Plugins & Middleware

• Opaque Dataplane Subject IDs (#5708) - Switched dataplane subjects to opaque identifiers.
• SQL Sanitizer Plugin (#5961) - Replaced the in-tree sql_sanitizer with cpex-sql-sanitizer.
• Auth-Context Middleware Refactor (#6008) - Extracted auth-context middleware registration into a testable submodule.

Fixed

Security, Auth & API

• RBAC Seeder Race (#4636) - Added unique constraints and migration remapping for active roles and user-role assignments, with savepoint/retry handling for concurrent bootstrap.
• CSRF Status Code (#5917) - Returned 401 for unauthenticated write requests instead of misleading 403 responses.
• LLM Settings CSRF (#5780) - Fixed CSRF failures when saving LLM settings in the Admin UI.
• Resource URI Conflict Message (#5920) - Showed a specific message for duplicate resource URI conflicts.
• Vite Rollup Fallback on s390x (#5779, #5836, #5958) - Fixed and force-installed the rollup fallback, including a Vite downgrade from 8 to 7 for s390x.
• CSRF Name Override Startup Warning (#6078) - Emitted a startup warning when CSRF_COOKIE_NAME or CSRF_TOKEN_NAME are overridden to non-default values, surfacing the misconfiguration at boot rather than at request time as intermittent 403 CSRF_TOKEN_INVALID errors.

Reliability & Infrastructure

• Redis Connection Leak (#5711) - Fixed a Redis connection leak.

• Health Check Recovery (#4862) - Increased health-check timeout from 5 seconds to 30 seconds and reset the failure counter after recovery.

• Docker Compose Startup (#5808) - Restored gateway HOST binding and fast-time-server startup.

• OAuth Callback JavaScript (#5997) - Removed a Python comment from JavaScript in the OAuth callback.

• DCR Client Uniqueness (#5198) - Removed a blocking unique constraint for multi-user DCR clients.

• Startup secret validation - JWT_SECRET_KEY are validated at startup with a minimum 32-byte length requirement and a comprehensive blocklist of known-weak values.The __REPLACE_ME__ placeholder value is always rejected and will block startup. Update the JWT_SECRET_KEY manually to a strong secret (length > 32).

• Hardened Helm chart defaults - JWT_SECRET_KEY in charts/mcp-stack/values.yaml now defaults to an empty string with deployment guidance, rather than shipping a sample weak key.

• Docker Compose and entrypoint hardening - Compose :? variable guards and entrypoint secret checks updated to match the new enforcement policy.

• Helm non-root container startup (#6041) - Set runAsUser for postgres (999), redis (999), and fast-time-server (1001) so pods with runAsNonRoot: true no longer fail with CreateContainerConfigError. Also corrected migration.image.tag from v1.0.6 to v1.0.7 to ensure the four new Alembic migrations are applied by the init job.

• E2E test view-modal race (#6084) - Re-checked the resources table and row count before reading the second row in the view-modal test, eliminating a re-render race that could cause a 60-second hang.

Changed

Security & Configuration

• JWT_SECRET_KEY placeholder rejection hardened (#6073) - The __REPLACE_ME__ placeholder value for JWT_SECRET_KEY is now unconditionally rejected at startup in all environments. Update the JWT_SECRET_KEY manually to a strong secret (length > 32).

Observability & Security

• Support bundle secret redaction (#6080) - Secret exclusion in generated bundles is now derived from the Settings model rather than a hand-maintained list, ensuring newly added secret-typed fields are automatically covered. Credentials are stripped from all string-valued *_url settings and *_URL environment variables uniformly. csrf_secret_key and identity_claims_secret are now typed as SecretStr.

Documentation

• OCP PGO Documentation (#5749) - Updated OCP PGO documentation.
• CSRF, Middleware, and LLM Admin Documentation (#5979) - Documented CSRF protection, middleware ordering, and LLM admin endpoints.
• Architecture Roadmap and Release History (#6037) - Updated the architecture roadmap and added release history.

Known Issues

• CSRF Validation Failure Saving LLM Provider/Model (#5739) - Saving an LLM Provider or Model in the Admin UI can fail with 403 CSRF validation failed. Recurrence of the class of failure documented in #5151.
  • Workaround: Copy CSRF_EXEMPT_PATHS from .env.example into .env and restart the application.
• LLM Chat Sessions Are In-Memory Only (#5740) - redis_client is hardcoded to None, so chat sessions are not shared across workers and are lost on process restart.
  • Workaround: Run a single worker (--workers 1) when session continuity is required.
• LLM Chat Cannot Connect to a Same-Gateway Virtual Server (#5215) - The forwarded session token is rejected with 401 when LLM Chat targets a virtual server on the same gateway instance.
• Tools Table Row Action Button Not Found (#5526) - The row action button is not found for the JSON-schema test tool in the Tools table.
