CVE-2026-87028 (GCVE-0-2026-87028)

Title
Cross-Board IDOR in the Board Custom Slot Preview in Concrete CMS 9.0.0 through 9.5.3 Discloses Restricted Page Summary Fields
Summary
Concrete CMS 9 through 9.5.3 did not confirm that a board InstanceItem submitted to the custom-slot preview endpoint belonged to the board instance the requesting user was authorized to edit, and did not enforce page-view permission before generating page-backed summary content. As a result, an authenticated user holding edit-board-contents permission on a single board instance could submit the identifier of an item belonging to a different board instance and receive summary fields, including the page title and description, of an underlying page the same user was otherwise forbidden to view. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.3 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N. Thanks Pakung for reporting.

Title
n8n: Cross-User Active Workflow ID and Lifecycle Event Disclosure via Missing userId Filter
Summary
n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the /rest/active-workflows endpoint returned every active workflow ID on the instance to any member regardless of sharing. Workflow activation, deactivation, and publication push events were also broadcast to clients that could not access the affected workflow, disclosing workflow IDs, version IDs, and activation error details. The affected paths include packages/cli/src/services/active-workflows.service.ts and packages/cli/src/workflows/workflow-push-notifier.service.ts. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.

Title
n8n: Log Streaming Event Destinations Decrypt Generic-Auth Credentials Without Ownership Check
Summary
n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, a Log Streaming event destination could reference a generic HTTP credential and decrypt whichever credential ID it named without an ownership check. A user with a custom global role carrying Log Streaming scopes could select a credential belonging to another project and send its decrypted secret to an attacker-controlled endpoint. The affected authorization boundary is packages/cli/src/modules/log-streaming.ee/destinations/destination-credentials-access.ts and the credential:read scope. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.

CVE-2026-86819 (GCVE-0-2026-86819)

Vulnerability from cvelistv5 – Published: 2026-09-08 20:22 – Updated: 2026-09-14 13:50

Title
Waves Central local privilege escalation via Improper XPC Client Authentication in macOS
Summary
Waves Central for macOS contains a local privilege escalation in the privileged helper service. The helper authorizes connecting XPC clients by comparing the caller's code-signing certificate chain for equality with its own, rather than validating the caller against a pinned code requirement (application identifier and Team ID). A local, authenticated user can execute code within the vendor-signed process, satisfy the helper's client check, and cause the helper to execute a script with root privileges. Fixed in 17.0.

Title
AlchemyCMS before 7.4.16 and 8.x before 8.3.6 Missing Authorization on GET /api/nodes
Summary
AlchemyCMS versions before 7.4.16 and 8.x before 8.3.6 fail to authorize access to the GET /api/nodes endpoint, allowing unauthenticated attackers to retrieve all navigation nodes. Attackers can access the endpoint without authentication to disclose restricted page names, URL paths, and internal URLs from all sites and languages.

Title
Snipe-IT 8.6.3 Authorization Bypass via Asset Update Endpoint
Summary
Snipe-IT versions before 8.7.0 fail to enforce checkout authorization when assignment fields are submitted to the asset update endpoint. Authenticated users with edit permission but explicitly denied checkout permission can reassign assets, bypass check-in procedures, and alter custody records by submitting assigned_user, assigned_asset, or assigned_location parameters to PATCH /api/v1/hardware/{id}.

Title
Snipe-IT 8.6.4 before 8.7.0 Permission Bypass via assigned components
Summary
Snipe-IT through 8.6.4 (fixed in 8.7.0) does not enforce the components.view permission on the authenticated endpoint GET /api/v1/hardware/<asset-id>/assigned/components. The endpoint authorizes only assets.view on the parent asset before returning linked component details; the components.view check is applied only to the response's available_actions.view flag and not to the returned data. As a result, an authenticated user holding only assets.view can enumerate component IDs, names, assigned quantities, and notes that are otherwise protected — the direct GET /api/v1/components/<id> endpoint correctly returns 403 Forbidden for such users.

CVE-2026-86762 (GCVE-0-2026-86762)

Title
Snipe-IT before 8.7.0 Authentication Bypass via API Middleware
Summary
Snipe-IT before 8.7.0 does not apply the CheckUserIsActivated middleware to the `api` middleware group in app/Http/Kernel.php, and deactivating a user does not revoke that user's Passport personal access tokens. As a result, although a deactivated account is correctly refused at web login, its existing API token continues to authenticate and to grant read and write access to the REST API (assets, users, licenses, etc.) at the account's prior permission level until the token expires. A deactivated account that retains user-management permissions can re-activate itself through the API, permanently defeating the deactivation control.

Mitigation
Architecture and Design
  • 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
Architecture and Design

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
Architecture and Design

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
Architecture and Design
  • 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
System Configuration Installation

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.
