Vulnerability from github – Published: 2026-01-09 09:31 – Updated: 2026-01-09 09:31The Schedule Post Changes With PublishPress Future plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.9.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with Contributor-level access and above, to create, update, delete, and publish malicious workflows that may automatically delete any post upon publication or update, including posts created by administrators.

GHSA-JXWR-G6R6-J3FX
Vulnerability from github – Published: 2026-05-11 14:04 – Updated: 2026-05-19 15:57Description
There's an IDOR in the channels message management system that allows authenticated users to modify or delete any message within channels they have read access to. The vulnerability exists in the message update and delete endpoints, which implement channel-level authorization but completely lack message ownership validation.
While the frontend correctly implements ownership checks (showing edit/delete buttons only for message owners or admins), the backend APIs bypass these protections by only validating channel access permissions without verifying that the requesting user owns the target message. This creates a client-side security control bypass where attackers can directly call the APIs to modify other users' messages.
The vulnerability affects both message content modification and deletion, allowing users to tamper with message integrity and audit trails in collaborative channel environments.
Source - Sink Analysis
Source: User-controlled message_id parameter in URL path
Call Chain:
1. FastAPI route handlers update_message_by_id() (line 450) and delete_message_by_id() (line 630) in backend/open_webui/routers/channels.py
2. Channel-level authorization check: has_access(user.id, type="read", access_control=channel.access_control) at lines 457 and 637
3. Message retrieval: Messages.get_message_by_id(message_id) at lines 467 and 647
4. Channel ID validation: if message.channel_id != id: at lines 472 and 652
5. Missing: Message ownership validation (message.user_id == user.id)
6. Sink: Messages.update_message_by_id(message_id, form_data) at line 476 or Messages.delete_message_by_id(message_id) at line 658 - modifies any message without ownership verification
Proof of Concept
- Deploy Open WebUI with channels enabled (
ENABLE_CHANNELS=true) - Create scenario:
- User A creates a channel and grants User B read access
- User A posts a message in the channel
- User B observes the message_id from the frontend
- Exploit: User B sends direct API requests bypassing frontend controls:
Message Update:
curl -X POST "http://localhost:8080/api/v1/channels/{channel_id}/messages/{victim_message_id}/update" \
-H "Authorization: Bearer {attacker_token}" \
-H "Content-Type: application/json" \
-d '{"content": "Malicious content injected by attacker"}'
Message Deletion:
curl -X DELETE "http://localhost:8080/api/v1/channels/{channel_id}/messages/{victim_message_id}/delete" \
-H "Authorization: Bearer {attacker_token}"
- Result: Victim's message is modified or deleted despite User B only having read permissions
Impact
- Users can modify other users' message content within shared channels
- Read-only users gain write/delete capabilities over other users' content
Remediation
Implement proper message ownership validation in the update and delete endpoints by adding ownership checks that follow the established security pattern used throughout the codebase. First, add a validation condition after the existing message retrieval to ensure only message owners or admins can modify messages: if user.role != "admin" and message.user_id != user.id and not has_access(user.id, type="write", access_control=channel.access_control) then raise a 403 Forbidden exception. Second, change the existing permission check from type="read" to type="write" for both update and delete operations to align with the access control model used in other routers (notes, prompts, knowledge, etc.).

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.
