The handler then calls `MemberService.update_role(workspace_id, user_id, body.role)` which sets the target member\u0027s role to whatever the request body specifies, with no check that the caller has owner-or-admin privilege, no check that the new role is not higher than the caller\u0027s own, and no check that the caller is not silently promoting themselves.\n**File:** `src/praisonai-platform/praisonai_platform/api/routes/workspaces.py`, lines 115-127; `services/member_service.py`, lines 55-69; `api/deps.py`, lines 54-73.\n**Root cause:** `require_workspace_member` exists with a `min_role` parameter (deps.py:58) but FastAPI\u0027s `Depends(require_workspace_member)` cannot pass arguments, so every route uses the default `\"member\"`. The route then passes the URL-supplied `user_id` and the body-supplied `role` directly to `MemberService.update_role`, which contains zero permission checks: it loads the member by composite key and assigns `member.role = new_role`.

The author\u0027s intent is also evident in `MemberService.has_role` (member_service.py:80-96), which implements an `owner \u003e admin \u003e member` hierarchy that this endpoint should be enforcing. The endpoint uses none of it. The `VALID_ROLES = {\"owner\", \"admin\", \"member\"}` enum check (member_service.py:62) only validates the *new role string is recognised*, not that the *caller has the right to assign it*. As a result, a member can write `{\"role\": \"owner\"}` to their own membership row and become owner in one PATCH.\n\n## Exploit Chain\n\n1. Attacker registers an account and joins (or is invited to) any workspace `W` as a \"member\" (the lowest privilege tier \u2014 typically anyone can be added by an owner during onboarding, or self-joins via an invite link). State: attacker has a JWT, is a `Member(workspace_id=W, user_id=attacker, role=\"member\")`.\n2. Attacker sends `PATCH /workspaces/W/members/\u003cattacker_user_id\u003e` with `Authorization: Bearer \u003cattacker_jwt\u003e` and body `{\"role\": \"owner\"}`. State: control flow enters `update_member_role`.\n3. `require_workspace_member(W, attacker)` runs. Its default `min_role=\"member\"` is satisfied because the attacker is a member. The dependency returns the attacker\u0027s identity. State: route handler proceeds with no further role gate.\n4. `MemberService.update_role(W, attacker, \"owner\")` runs. `VALID_ROLES` accepts `\"owner\"`. `self.get(W, attacker)` returns the attacker\u0027s existing member row. The next line, `member.role = \"owner\"`, mutates the attacker\u0027s role in place. `await self._session.flush()` commits. State: attacker is now `Member(workspace_id=W, user_id=attacker, role=\"owner\")`.\n5. Attacker re-issues `GET /auth/me` (or any owner-gated endpoint) and is now treated as workspace owner. State: full administrative control of the workspace, including the ability to add/remove members, change settings, delete the workspace, and exfiltrate everything via the agent/issue/project/comment IDORs that were filed as separate advisories.\n6. Final state: starting from the lowest workspace privilege, the attacker holds owner of the workspace within one HTTP request. The same primitive also lets the attacker DEMOTE the legitimate owner by sending `PATCH /workspaces/W/members/\u003cowner_user_id\u003e` with `{\"role\": \"member\"}` \u2014 owner lockout in two requests total.\n\n## Security Impact\n\n**Severity:** sec-critical. CVSS 9.1: network attack, low complexity, low privileges (the lowest tier on the platform), no user interaction, scope changed (the privilege boundary the attacker crosses is the workspace owner, a different security principal), high confidentiality and integrity (full workspace control), no availability claim (the attacker can also DELETE the workspace via the companion `delete_workspace` advisory, but that is a separate finding).\n**Attacker capability:** with one workspace-member token plus one PATCH request, the attacker becomes workspace owner. From there: add/remove any user as owner, change every workspace setting (including the `settings` JSON blob), demote the legitimate owner to \"member\", or chain into the companion `delete_workspace` advisory to wipe the workspace entirely. In multi-tenant SaaS deployments where any signup yields a member-level account in some default workspace, this is effectively pre-auth.\n**Preconditions:** `praisonai-platform` is deployed multi-tenant (more than one workspace exists OR the deployment grants member access on signup); the attacker has any membership token in the target workspace.\n**Differential:** source-inspection-verified end-to-end. The asymmetry between `require_workspace_member`\u0027s `min_role` parameter (which exists, defaults to \"member\", and is never overridden) and `MemberService.has_role`\u0027s clearly tiered `owner \u003e admin \u003e member` hierarchy (which exists but is never invoked with anything but the default) is the smoking gun. With the suggested fix below, the route resolves with `min_role=\"owner\"`, the attacker\u0027s member-level token fails the gate at the dependency, and the privilege escalation never reaches the service layer.\n\n## Suggested Fix\n\nThe fix has two parts. First, the route must resolve `require_workspace_member` with `min_role=\"owner\"` (or at least `\"admin\"`). Second, `MemberService.update_role` should refuse to set a target\u0027s role higher than the caller\u0027s own role, so that an admin cannot accidentally produce another owner.\n\n```diff\n--- a/src/praisonai-platform/praisonai_platform/api/routes/workspaces.py\n+++ b/src/praisonai-platform/praisonai_platform/api/routes/workspaces.py\n@@ -115,11 +115,16 @@\n+def _require_owner(workspace_id: str, user, session):\n+    return require_workspace_member(workspace_id, user, session, min_role=\"owner\")\n+\n @router.patch(\"/{workspace_id}/members/{user_id}\", response_model=MemberResponse)\n async def update_member_role(\n     workspace_id: str,\n     user_id: str,\n     body: MemberUpdate,\n-    user: AuthIdentity = Depends(require_workspace_member),\n+    user: AuthIdentity = Depends(_require_owner),\n     session: AsyncSession = Depends(get_db),\n ):\n     member_svc = MemberService(session)\n+    if not await member_svc.has_role(workspace_id, user.id, \"owner\"):\n+        raise HTTPException(status_code=403, detail=\"Only owners can change member roles\")\n     member = await member_svc.update_role(workspace_id, user_id, body.role)\n```\n\nDefence-in-depth in the service layer:\n\n```diff\n--- a/src/praisonai-platform/praisonai_platform/services/member_service.py\n+++ b/src/praisonai-platform/praisonai_platform/services/member_service.py\n@@ -55,7 +55,7 @@\n-    async def update_role(self, workspace_id: str, user_id: str, new_role: str) -\u003e Optional[Member]:\n+    async def update_role(self, workspace_id: str, caller_id: str, user_id: str, new_role: str) -\u003e Optional[Member]:\n         \"\"\"Update a member\u0027s role.\"\"\"\n+        if not await self.has_role(workspace_id, caller_id, \"owner\"):\n+            raise PermissionError(\"Only owners can update member roles\")\n         if new_role not in VALID_ROLES:\n             raise ValueError(...)\n```\n\nThe companion endpoints `add_member`, `remove_member`, `delete_workspace`, and `update_workspace` exhibit the same `Depends(require_workspace_member)` default-min-role pattern and are filed as their own advisories so each gets a separate CVE.",

Attacker sends `PATCH /workspaces/W/members/\u003cattacker_user_id\u003e` with `Authorization: Bearer \u003cattacker_jwt\u003e` and body `{\"role\": \"owner\"}`. State: control flow enters `update_member_role`.\n3. `require_workspace_member(W, attacker)` runs. Its default `min_role=\"member\"` is satisfied because the attacker is a member. The dependency returns the attacker\u0027s identity. State: route handler proceeds with no further role gate.\n4. `MemberService.update_role(W, attacker, \"owner\")` runs. `VALID_ROLES` accepts `\"owner\"`. `self.get(W, attacker)` returns the attacker\u0027s existing member row. The next line, `member.role = \"owner\"`, mutates the attacker\u0027s role in place. `await self._session.flush()` commits. State: attacker is now `Member(workspace_id=W, user_id=attacker, role=\"owner\")`.\n5. Attacker re-issues `GET /auth/me` (or any owner-gated endpoint) and is now treated as workspace owner. State: full administrative control of the workspace, including the ability to add/remove members, change settings, delete the workspace, and exfiltrate everything via the agent/issue/project/comment IDORs that were filed as separate advisories.\n6. Final state: starting from the lowest workspace privilege, the attacker holds owner of the workspace within one HTTP request. The same primitive also lets the attacker DEMOTE the legitimate owner by sending `PATCH /workspaces/W/members/\u003cowner_user_id\u003e` with `{\"role\": \"member\"}` \u2014 owner lockout in two requests total.\n\n## Security Impact\n\n**Severity:** sec-critical. CVSS 9.1: network attack, low complexity, low privileges (the lowest tier on the platform), no user interaction, scope changed (the privilege boundary the attacker crosses is the workspace owner, a different security principal), high confidentiality and integrity (full workspace control), no availability claim (the attacker can also DELETE the workspace via the companion `delete_workspace` advisory, but that is a separate finding).\n**Attacker capability:** with one workspace-member token plus one PATCH request, the attacker becomes workspace owner. From there: add/remove any user as owner, change every workspace setting (including the `settings` JSON blob), demote the legitimate owner to \"member\", or chain into the companion `delete_workspace` advisory to wipe the workspace entirely. In multi-tenant SaaS deployments where any signup yields a member-level account in some default workspace, this is effectively pre-auth.\n**Preconditions:** `praisonai-platform` is deployed multi-tenant (more than one workspace exists OR the deployment grants member access on signup); the attacker has any membership token in the target workspace.\n**Differential:** source-inspection-verified end-to-end. The asymmetry between `require_workspace_member`\u0027s `min_role` parameter (which exists, defaults to \"member\", and is never overridden) and `MemberService.has_role`\u0027s clearly tiered `owner \u003e admin \u003e member` hierarchy (which exists but is never invoked with anything but the default) is the smoking gun. With the suggested fix below, the route resolves with `min_role=\"owner\"`, the attacker\u0027s member-level token fails the gate at the dependency, and the privilege escalation never reaches the service layer.\n\n## Suggested Fix\n\nThe fix has two parts. First, the route must resolve `require_workspace_member` with `min_role=\"owner\"` (or at least `\"admin\"`). Second, `MemberService.update_role` should refuse to set a target\u0027s role higher than the caller\u0027s own role, so that an admin cannot accidentally produce another owner.\n\n```diff\n--- a/src/praisonai-platform/praisonai_platform/api/routes/workspaces.py\n +++ b/src/praisonai-platform/praisonai_platform/api/routes/workspaces.py\n@@ -115,11 +115,16 @@\n+def _require_owner(workspace_id: str, user, session):\n+    return require_workspace_member(workspace_id, user, session, min_role=\"owner\")\n+\n @router.patch(\"/{workspace_id}/members/{user_id}\", response_model=MemberResponse)\n async def update_member_role(\n     workspace_id: str,\n     user_id: str,\n     body: MemberUpdate,\n-    user: AuthIdentity = Depends(require_workspace_member),\n+    user: AuthIdentity = Depends(_require_owner),\n     session: AsyncSession = Depends(get_db),\n ):\n     member_svc = MemberService(session)\n+    if not await member_svc.has_role(workspace_id, user.id, \"owner\"):\n+        raise HTTPException(status_code=403, detail=\"Only owners can change member roles\")\n     member = await member_svc.update_role(workspace_id, user_id, body.role)\n```\n\nDefence-in-depth in the service layer:\n\n```diff\n --- a/src/praisonai-platform/praisonai_platform/services/member_service.py\n+++ b/src/praisonai-platform/praisonai_platform/services/member_service.py\n@@ -55,7 +55,7 @@\n-    async def update_role(self, workspace_id: str, user_id: str, new_role: str) -\u003e Optional[Member]:\n+    async def update_role(self, workspace_id: str, caller_id: str, user_id: str, new_role: str) -\u003e Optional[Member]:\n         \"\"\"Update a member\u0027s role.\"\"\"\n+        if not await self.has_role(workspace_id, caller_id, \"owner\"):\n+            raise PermissionError(\"Only owners can update member roles\")\n         if new_role not in VALID_ROLES:\n             raise ValueError(...)\n ```\n\nThe companion endpoints `add_member`, `remove_member`, `delete_workspace`, and `update_workspace` exhibit the same `Depends(require_workspace_member)` default-min-role pattern and are filed as their own advisories so each gets a separate CVE.",
