GHSA-HQRG-CFXF-RJG9
Vulnerability from github – Published: 2026-04-10 03:31 – Updated: 2026-04-10 03:31The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to an Insecure Direct Object Reference in all versions up to, and including, 3.9.7. This is due to missing authentication and authorization checks in the pay_incomplete_order() function. The function accepts an attacker-controlled order_id parameter and uses it to look up order data, then writes billing fields to the order owner's profile ($order_data->user_id) without verifying the requester's identity or ownership. Because the Tutor nonce (_tutor_nonce) is exposed on public frontend pages, this makes it possible for unauthenticated attackers to overwrite the billing profile (name, email, phone, address) of any user who has an incomplete manual order, by sending a crafted POST request with a guessed or enumerated order_id.

GHSA-HR43-RJMR-7WMM
Vulnerability from github – Published: 2026-05-08 19:38 – Updated: 2026-05-15 23:52Mass Assignment via Pydantic extra='allow' Allows Creating Folders in Other Users' Accounts
Affected Component
Folder creation endpoint and form model:
- backend/open_webui/models/folders.py (lines 72-77, FolderForm with extra='allow')
- backend/open_webui/models/folders.py (lines 95-106, insert_new_folder dict construction)
- backend/open_webui/routers/folders.py (line 119, create_folder endpoint)
Affected Versions
Current main branch (commit 6fdd19bf1) and likely all versions since FolderForm adopted extra='allow'.
Description
FolderForm uses model_config = ConfigDict(extra='allow'), which permits arbitrary fields to pass through Pydantic validation and be included in model_dump(exclude_unset=True). In insert_new_folder, the server-assigned user_id is placed at the start of the dict and then overwritten by the spread of form data:
# models/folders.py:95-106
folder = FolderModel(
**{
'id': id, # server
'user_id': user_id, # server — overwritten below
**(form_data.model_dump(exclude_unset=True) or {}), # user-controlled (extra='allow')
'parent_id': parent_id,
'created_at': int(time.time()),
'updated_at': int(time.time()),
}
)
Because FolderModel declares user_id: str as a real field (not just a form extra), any attacker-supplied user_id in the POST body is accepted by the model and persisted on the Folder row.
Attack Scenario
- Attacker discovers a victim's user ID. User UUIDs commonly leak via the user search endpoint (
GET /api/v1/users/search, intentionally accessible to verified users for sharing UI), shared chat metadata, or channel member lists. - Attacker sends:
POST /api/v1/folders/ { "name": "Important: Click here", "user_id": "<victim_user_id>", "meta": {"icon": "warning"}, "data": {...} } - Pydantic accepts the extra
user_idfield (allowed byextra='allow'). insert_new_folderspreads the form data over the server-set'user_id': user_id, overwriting it with the attacker's value.- The
Folderrow is persisted withuser_id = <victim_user_id>. - The victim sees the attacker-planted folder in their UI on next load because
GET /api/v1/folders/filters by the viewer's ownuser_id.
The attacker can repeat this to plant multiple folders, use crafted name values for phishing ("Click here to recover account" / "Security alert"), and abuse the meta and data fields to add visual elements that further mimic legitimate content.
Impact
- Unauthorized write into victim's folder tree
- Phishing surface: attacker-controlled
name,meta, anddatarender in the victim's UI in a trusted context - DoS / spam: attacker can flood a victim with arbitrary folders; victim must manually delete each one
- Attacker cannot read the folder back — all read paths filter by the caller's own
user_id— so confidentiality is preserved, but integrity and trust are compromised
Preconditions
- Attacker must have an authenticated account with
features.folderspermission (default for all users) - Attacker must know or guess the victim's user UUID (obtainable through various non-sensitive endpoints)

"details": "# Mass Assignment via Pydantic extra=\u0027allow\u0027 Allows Creating Folders in Other Users\u0027 Accounts\n\n## Affected Component\n\nFolder creation endpoint and form model:\n- `backend/open_webui/models/folders.py` (lines 72-77, `FolderForm` with `extra=\u0027allow\u0027`)\n- `backend/open_webui/models/folders.py` (lines 95-106, `insert_new_folder` dict construction)\n- `backend/open_webui/routers/folders.py` (line 119, `create_folder` endpoint)\n\n## Affected Versions\n\nCurrent main branch (commit `6fdd19bf1`) and likely all versions since `FolderForm` adopted `extra=\u0027allow\u0027`.\n\n## Description\n\n`FolderForm` uses `model_config = ConfigDict(extra=\u0027allow\u0027)`, which permits arbitrary fields to pass through Pydantic validation and be included in `model_dump(exclude_unset=True)`. In `insert_new_folder`, the server-assigned `user_id` is placed at the start of the dict and then overwritten by the spread of form data:\n\n```python\n# models/folders.py:95-106\nfolder = FolderModel(\n **{\n \u0027id\u0027: id, # server\n \u0027user_id\u0027: user_id, # server \u2014 overwritten below\n **(form_data.model_dump(exclude_unset=True) or {}), # user-controlled (extra=\u0027allow\u0027)\n \u0027parent_id\u0027: parent_id,\n \u0027created_at\u0027: int(time.time()),\n \u0027updated_at\u0027: int(time.time()),\n }\n)\n```\n\nBecause `FolderModel` declares `user_id: str` as a real field (not just a form extra), any attacker-supplied `user_id` in the POST body is accepted by the model and persisted on the `Folder` row.\n\n## Attack Scenario\n\n1. Attacker discovers a victim\u0027s user ID. User UUIDs commonly leak via the user search endpoint (`GET /api/v1/users/search`, intentionally accessible to verified users for sharing UI), shared chat metadata, or channel member lists.\n2. Attacker sends:\n ```\n POST /api/v1/folders/\n {\n \"name\": \"Important: Click here\",\n \"user_id\": \"\u003cvictim_user_id\u003e\",\n \"meta\": {\"icon\": \"warning\"},\n \"data\": {...}\n }\n ```\n3. Pydantic accepts the extra `user_id` field (allowed by `extra=\u0027allow\u0027`).\n4. `insert_new_folder` spreads the form data over the server-set `\u0027user_id\u0027: user_id`, overwriting it with the attacker\u0027s value.\n5. The `Folder` row is persisted with `user_id = \u003cvictim_user_id\u003e`.\n6. The victim sees the attacker-planted folder in their UI on next load because `GET /api/v1/folders/` filters by the viewer\u0027s own `user_id`.\n\nThe attacker can repeat this to plant multiple folders, use crafted `name` values for phishing (\"Click here to recover account\" / \"Security alert\"), and abuse the `meta` and `data` fields to add visual elements that further mimic legitimate content.\n\n## Impact\n\n- Unauthorized write into victim\u0027s folder tree\n- Phishing surface: attacker-controlled `name`, `meta`, and `data` render in the victim\u0027s UI in a trusted context\n- DoS / spam: attacker can flood a victim with arbitrary folders; victim must manually delete each one\n- Attacker cannot read the folder back \u2014 all read paths filter by the caller\u0027s own `user_id` \u2014 so confidentiality is preserved, but integrity and trust are compromised\n\n## Preconditions\n\n- Attacker must have an authenticated account with `features.folders` permission (default for all users)\n- Attacker must know or guess the victim\u0027s user UUID (obtainable through various non-sensitive endpoints)",

Mitigation
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation MIT-4.4
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
CAPEC-665: Exploitation of Thunderbolt Protection Flaws
An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
