ComfyUI-Manager/CHANGELOG.md

Changelog

All notable changes to ComfyUI-Manager are documented in this file.

The format is based on Keep a Changelog 1.1.0, and this project adheres to Semantic Versioning 2.0.0.

4.2.1 - 2026-04-22

Added

• Server-push feature flag extension.manager.supports_csrf_post registered at startup, allowing ComfyUI-frontend (and other clients) to detect CSRF-POST backend support as a semantic capability contract, without relying on version string parsing. Pre-4.2.1 Manager does not set the flag — clients should treat its absence as 'incompatible with NEW_UI'.

Unreleased

Security-hardening release on branch fix/csrf-post-conversion. Contains breaking-ish API changes for state-mutating endpoints. See Migration notes below before upgrading programmatic clients.

Security

• CSRF Content-Type gate: 18 state-mutation POST handlers (9 in glob, 9 in legacy) now reject the three CORS "simple request" Content-Types (application/x-www-form-urlencoded, multipart/form-data, text/plain). This closes the residual <form method="POST"> bypass route that remained after the GET→POST transition. Legitimate clients using application/json (or no body) are unaffected.
• do_fix security level raised from high to high+: aligns the enforcement gate (is_allowed_security_level) with the log text emitted by SECURITY_MESSAGE_HIGH_P. Both glob/manager_server.py and legacy/manager_server.py updated in lockstep. Environments running at security_level = high can no longer fix a nodepack — use security_level = normal or lower.
• Config setters now gated at middle security level: POST /v2/manager/db_mode, POST /v2/manager/policy/update, and POST /v2/manager/channel_url_list now check is_allowed_security_level('middle') before mutating configuration (both glob and legacy). Closes a pre-existing gap where the write path was reachable at any security level. Reads (GET) remain unrestricted.

Changed

• State-changing endpoints converted from GET to POST (CSRF hardening): /v2/manager/queue/{update_all, reset, start, update_comfyui}, /v2/snapshot/{remove, restore, save}, /v2/comfyui_manager/comfyui_switch_version, /v2/manager/reboot. Query-string parameters are preserved where they existed; only the HTTP method changes.
• POST /v2/comfyui_manager/comfyui_switch_version parameters moved from query string to JSON body (REST idiom + body-reading CSRF posture): The handler now consumes application/json with the body shape {"ver": "...", "client_id": "...", "ui_id": "..."} instead of reading ?ver=...&client_id=...&ui_id=... from the URL. Because body-reading handlers are already covered by the CORS-preflight mechanism for cross-origin protection, the Content-Type rejection gate introduced for the other state-mutation endpoints is intentionally NOT applied here (see comfyui_manager/common/manager_security.py module docstring). The first-party JS client in comfyui_manager/js/comfyui-manager.js was updated in the same change; third-party callers must migrate.
• Config endpoints split into GET (read) + POST (write): /v2/manager/{db_mode, policy/update, channel_url_list}. GET returns the current value; POST accepts a JSON body {"value": "..."}. The prior single-method form that accepted a ?value=... query parameter on either verb is retired.
• openapi.yaml fully resynchronized with the server: HTTP methods, the dual-method splits above, request-body schemas for the new POST setters, and the TaskHistoryItem.params field now match manager_server.py.
• Legacy restart(self) → restart(request): parameter name corrected. No behavioral change.

Added

• E2E test harness variants for security-level and legacy-mode scenarios: tests/e2e/scripts/start_comfyui_legacy.sh, tests/e2e/scripts/start_comfyui_permissive.sh, tests/e2e/scripts/start_comfyui_strict.sh. See docs/guide/GUIDE_E2E_TEST.md for usage.
• COMFYUI_MANAGER_SKIP_MANAGER_REQUIREMENTS environment variable: when set, skips the manager_requirements.txt reinstall path. Intended for E2E environments where those dependencies are provisioned separately.
• TaskHistoryItem.params field (Pydantic + openapi.yaml): mirrors QueueTaskItem.params so that task history retains the original request payload (nullable when unavailable).
• Automated endpoint coverage — pytest E2E + Playwright specs covering all 39 unique (method, path) endpoints across glob and legacy. Coverage is tracked in reports/api-coverage-matrix.md and reports/e2e_test_coverage.md.

Removed

• Legacy per-operation POST routes consolidated into POST /v2/manager/queue/batch: /v2/manager/queue/{install, uninstall, update, fix, disable, reinstall, abort_current}. The first-party JS client already uses queue/batch; only third-party scripts that call the per-operation routes directly are affected.
• GET /manager/notice (v1, pip-install redirect banner). GET /v2/manager/notice remains available.

Migration notes

• Third-party clients calling POST /v2/manager/queue/install (and the other per-operation queue routes) must switch to POST /v2/manager/queue/batch with a body such as {"install": [{id, ver, ...}], "batch_id": "..."}. See reports/endpoint_scenarios.md for the full payload shape.
• Programmatic clients that posted to the CSRF-hardened endpoints with application/x-www-form-urlencoded, multipart/form-data, or text/plain must switch to application/json (or omit the body entirely when the endpoint takes its parameters from the query string).
• Clients that called any of the methods listed under Changed → State-changing endpoints with GET must switch to POST. Query parameters remain valid.
• Clients that wrote configuration via GET /v2/manager/{db_mode, policy/update, channel_url_list}?value=... must switch to POST with JSON body {"value": "..."}.
• Third-party scripts calling POST /v2/comfyui_manager/comfyui_switch_version?ver=...&client_id=...&ui_id=... must switch to POST with Content-Type: application/json and body {"ver": "...", "client_id": "...", "ui_id": "..."}. The query-string form no longer works.
• Environments running at security_level = high can no longer run do_fix. Either lower the security level (normal, normal-, or weak as appropriate) or skip the fix operation.
• Environments running at security_level = high can no longer mutate db_mode, policy/update, or channel_url_list via POST (returns 403). Lower the security level to normal or below to change configuration, or perform the change from a trusted entry point. Read access via GET is unaffected.
