CVE-2026-47415

Description

## Summary **Type:** Insecure Direct Object Reference. The issue CRUD endpoints (`GET / PATCH / DELETE /workspaces/{workspace_id}/issues/{issue_id}`) gate access on `require_workspace_member(workspace_id)` only, then resolve `issue_id` through `IssueService.get(issue_id)` which is a primary-key lookup with no workspace constraint. A user who is a member of any workspace `W1` can read, modify, or delete issues that belong to a different workspace `W2`. **File:** `src/praisonai-platform/praisonai_platform/services/issue_service.py`, lines 72-156; route handlers at `src/praisonai-platform/praisonai_platform/api/routes/issues.py`, lines 82-137. **Root cause:** the route extracts `workspace_id` from the URL path, uses it solely for the membership gate, then calls `IssueService.get(issue_id)` / `IssueService.update(issue_id, ...)` / `IssueService.delete(issue_id)` without re-checking which workspace the issue actually belongs to. `IssueService.get` runs a single-key lookup; `update` and `delete` call `self.get(issue_id)` first and then mutate the returned row, inheriting the same gap. The `MemberService` in this same codebase uses a composite `(workspace_id, user_id)` key, proving the author knows the safe pattern; it was simply not applied to the issue, agent, project, comment, or label services. ## Affected Code **File 1:** `src/praisonai-platform/praisonai_platform/services/issue_service.py`, lines 72-75 and 97-156. ```python class IssueService: ... async def get(self, issue_id: str) -> Optional[Issue]: """Get issue by ID.""" return await self._session.get(Issue, issue_id) # <-- BUG: no workspace_id predicate async def update( self, issue_id: str, title: Optional[str] = None, ... ) -> Optional[Issue]: issue = await self.get(issue_id) # <-- inherits the same gap if issue is None: return None ... return issue async def delete(self, issue_id: str) -> bool: issue = await self.get(issue_id) # <-- inherits the same gap if issue is None: return False await self._session.delete(issue) await self._session.flush() return True ``` **File 2:** `src/praisonai-platform/praisonai_platform/api/routes/issues.py`, lines 82-137. ```python @router.get("/{issue_id}", response_model=IssueResponse) async def get_issue( workspace_id: str, issue_id: str, user: AuthIdentity = Depends(require_workspace_member), # only checks membership in workspace_id session: AsyncSession = Depends(get_db), ): svc = IssueService(session) issue = await svc.get(issue_id) # <-- workspace_id never threaded through if issue is None: raise HTTPException(status_code=404, detail="Issue not found") return IssueResponse.model_validate(issue) @router.patch("/{issue_id}", response_model=IssueResponse) async def update_issue( workspace_id: str, issue_id: str, body: IssueUpdate, user: AuthIdentity = Depends(require_workspace_member), session: AsyncSession = Depends(get_db), ): svc = IssueService(session) issue = await svc.update( # <-- writes to any issue in the DB issue_id, title=body.title, description=body.description, status=body.status, priority=body.priority, assignee_type=body.assignee_type, assignee_id=body.assignee_id, project_id=body.project_id, ) ... ``` `delete_issue` (lines 127-137) repeats the pattern. **Why it's wrong:** `workspace_id` from the route is used solely as a membership predicate ("are you in some workspace W?"), never as a resource-ownership predicate ("is the issue you are addressing actually inside W?"). The standard FastAPI/SQLAlchemy fix is to make the resource-lookup query include the workspace constraint and treat absence as 404, so a foreign-workspace issue is indistinguishable from a non-existent one. The `update_issue` handler additionally allows the attacker to overwrite `project_id`, which can re-assign the foreign issue to an unrelated project the attacker also does not own — escalating the scope of the write primitive. ## Exploit Chain 1. Attacker registers a workspace `W_attacker` (where they are a member) and harvests a target issue UUID `I_T` from any side channel: the activity feed (`activity.py:log` records `issue_id=...`), comment threads, error messages, exported issue dumps, issue mentions in agent prompts, or operator screenshots. Issue IDs are uuid4 strings but they are not secret. State: attacker holds `I_T`. 2. Attacker authenticates and POSTs `Authorization: Bearer <attacker_jwt>` to `GET /workspaces/W_attacker/issues/I_T`. `require_workspace_member(W_attacker, attacker)` passes (attacker is a member of `W_attacker`). State: control flow enters `get_issue` with `workspace_id=W_attacker, issue_id=I_T`. 3. `IssueService.get(I_T)` runs `session.get(Issue, "I_T")`, which is `SELECT * FROM issues WHERE id = 'I_T' LIMIT 1` with no `workspace_id = 'W_attacker'` filter. The row is returned in full — including `title`, `description` (often confidential bug-report content, customer PII, embedded credentials, or internal roadmap data), `status`, `priority`, `assignee_id`, `created_by`, and `project_id`. State: response body is the JSON-serialised foreign issue. 4. Attacker repeats with `PATCH /workspaces/W_attacker/issues/I_T` and a body of `{"description": "<reset>", "status": "closed", "project_id": "<arbitrary>"}`. `update_issue` calls `svc.update(I_T, ...)` which loads the target row and mutates the listed fields. State: the foreign workspace's issue is silently re-described, re-statused, and re-projected. 5. Attacker calls `DELETE /workspaces/W_attacker/issues/I_T` to destroy the target issue. `IssueService.delete` loads the row and calls `session.delete()`. State: target issue is gone from the foreign workspace. 6. Final state: any attacker with one workspace-member token can enumerate, exfiltrate, rewrite, and delete every issue in the multi-tenant deployment given the issue UUIDs (which leak through the side channels above). The `act_svc.log(workspace_id, "issue.updated", "issue", issue.id, ...)` call at line 118 records the event under `W_attacker` rather than `W_target`, so the foreign workspace's audit trail does not record the tampering — making detection harder. ## Security Impact **Severity:** sec-high. CVSS 8.1: network attack, low complexity, low privileges (any workspace member), no user interaction, scope unchanged, high confidentiality (full issue body including any embedded secrets), high integrity (arbitrary writes including project re-assignment), low availability (DELETE wipes target issues). **Attacker capability:** with one workspace-member token plus a harvested issue UUID, an attacker reads the target issue's `title`, `description`, `status`, `priority`, `assignee_id`, and `project_id`; rewrites any of those fields (silent edit, false closure, malicious re-assignment); re-projects the issue to an unrelated project to confuse triagers; or deletes the issue altogether to destroy evidence of customer reports. **Preconditions:** `praisonai-platform` is deployed multi-tenant; the attacker has any membership token; the target issue's UUID is known or guessable (UUIDs leak through activity feeds, comment threads, error messages, exported dumps, and operator screenshots). **Differential:** source-inspection-verified end-to-end. The asymmetry between `IssueService.get(issue_id)` (no workspace check) and `MemberService.get(workspace_id, user_id)` (composite key check) in the same codebase confirms the pattern. With the suggested fix below applied, `IssueService.get(workspace_id, issue_id)` returns `None` for foreign-workspace issues, the route handler returns 404, and the foreign data is indistinguishable from a missing record. ## Suggested Fix Make every single-row resource lookup take the workspace predicate; treat foreign-workspace rows as 404. ```diff --- a/src/praisonai-platform/praisonai_platform/services/issue_service.py +++ b/src/praisonai-platform/praisonai_platform/services/issue_service.py @@ -69,9 +69,12 @@ class IssueService: await self._session.flush() return issue - async def get(self, issue_id: str) -> Optional[Issue]: - """Get issue by ID.""" - return await self._session.get(Issue, issue_id) + async def get(self, workspace_id: str, issue_id: str) -> Optional[Issue]: + """Get issue by ID, scoped to a workspace.""" + stmt = select(Issue).where( + Issue.id == issue_id, Issue.workspace_id == workspace_id + ) + return (await self._session.execute(stmt)).scalar_one_or_none() async def update( self, + workspace_id: str, issue_id: str, ... ) -> Optional[Issue]: - issue = await self.get(issue_id) + issue = await self.get(workspace_id, issue_id) ... - async def delete(self, issue_id: str) -> bool: + async def delete(self, workspace_id: str, issue_id: str) -> bool: - issue = await self.get(issue_id) + issue = await self.get(workspace_id, issue_id) ``` Update the route handlers in `routes/issues.py` to thread `workspace_id` through. The same pattern (single-key resource lookup gated only by workspace-member check) exists in `AgentService`, `ProjectService`, `CommentService`, and `LabelService`; each is a separate exploitable IDOR and should be filed as its own advisory so each gets a CVE.
