Title
Snipe-IT before 8.7.0 Authorization Bypass via OAuth Clients
Summary
Snipe-IT before 8.7.0 fails to properly gate Laravel Passport's OAuth client management routes, allowing any authenticated user to register OAuth clients with attacker-controlled redirect URIs. Attackers can trick administrators into approving consent screens, then exchange authorization codes for bearer tokens inheriting full admin API permissions lasting up to 40 years.

Title
snipe-it before 8.7.0 Business Logic Bypass via asset_model endpoint
Summary
snipe-it versions before 8.7.0 fail to validate the requestable flag for asset models in the POST /account/request/asset_model/{modelId} endpoint. Authenticated users can bypass administrative restrictions and create checkout requests for non-requestable asset models by submitting requests directly to the endpoint.

CVE-2026-86752 (GCVE-0-2026-86752)

Vulnerability from cvelistv5 – Published: 2026-09-09 13:32 – Updated: 2026-09-10 14:57
VLAI
Title
snipe-it before 8.7.0 Authorization Bypass via Asset Audit Endpoints
Summary
snipe-it versions before 8.7.0 fail to enforce per-instance FMCS scoping in asset audit endpoints, relying solely on query-layer filtering instead of policy-layer authorization checks. Attackers with valid sessions and assets.audit permissions could write audit log entries against cross-company assets if the query-layer scope were bypassed or refactored.

CVE-2026-86750 (GCVE-0-2026-86750)

Title
snipe-it before 8.7.0 Authorization Bypass via API User Create/Update
Summary
Snipe-IT versions <= 8.6.3 (fixed in 8.7.0) do not validate company assignment authorization before persisting user records via the REST API. In Api\UsersController::store() and ::update(), the user record is filled from the request and saved before the requested company_id / company_ids[] values are filtered against the actor's permitted companies (Company::getIdsForCurrentUser()). On installs using Full Multiple Companies Support (FMCS), a non-superuser holding users.create (or users.edit on a target user) can submit company identifiers for companies outside their scope — including a mix of permitted and foreign ids — causing the account row to be committed to the database before authorization is checked. Where null_company_is_floater=1 is set, the post-hoc filter leaves an empty company pivot and the account is persisted as a "floater" with cross-company visibility, allowing creation or relocation of user accounts across tenant boundaries.

Title
snipe-it before 8.7.0 Authorization Bypass via Pivot-Only User
Summary
Snipe-IT is an open source IT asset management system. In versions up to and including 8.6.3, the report acceptance endpoints POST /reports/unaccepted_assets/sent_reminder (ReportsController::sentAssetAcceptanceReminder) and DELETE /reports/unaccepted_assets/{acceptanceId}/delete (ReportsController::deleteAssetAcceptance) are not correctly scoped when Full Multiple Company Support (FMCS) is enabled. In 8.6.3 the guard ReportsController::currentUserCanAccessAcceptance() early-exits with 'return true' when '! $user->company_id' is truthy, which is the case for every pivot-only user (a user associated with companies through the company_user pivot table whose scalar users.company_id column is NULL); versions prior to 8.6.3 lacked the guard altogether. As a result, an authenticated user holding the reports.view permission can send acceptance-reminder emails for, and permanently delete, any pending acceptance record in the install regardless of which company owns the underlying checkoutable. Deletion is destructive and forfeits the acceptance audit trail for the affected item, and the reminder email exposes limited cross-company acceptance context (item name and assignment metadata) to the recipient. Acceptance IDs are sequential integers and can be enumerated. This issue is fixed in version 8.7.0.

In versions up to and including 8.6.3, the report acceptance endpoints POST /reports/unaccepted_assets/sent_reminder (ReportsController::sentAssetAcceptanceReminder) and DELETE /reports/unaccepted_assets/{acceptanceId}/delete (ReportsController::deleteAssetAcceptance) are not correctly scoped when Full Multiple Company Support (FMCS) is enabled. In 8.6.3 the guard ReportsController::currentUserCanAccessAcceptance() early-exits with \u0027return true\u0027 when \u0027! $user-\u003ecompany_id\u0027 is truthy, which is the case for every pivot-only user (a user associated with companies through the company_user pivot table whose scalar users.company_id column is NULL); versions prior to 8.6.3 lacked the guard altogether. As a result, an authenticated user holding the reports.view permission can send acceptance-reminder emails for, and permanently delete, any pending acceptance record in the install regardless of which company owns the underlying checkoutable. Deletion is destructive and forfeits the acceptance audit trail for the affected item, and the reminder email exposes limited cross-company acceptance context (item name and assignment metadata) to the recipient. Acceptance IDs are sequential integers and can be enumerated. This issue is fixed in version 8.7.0."

Title
Lara Dashboard before 1.3.2 Incorrect Authorization in Core-Upgrade Archive Upload
Summary
Lara Dashboard before 1.3.2 authorizes the POST /admin/settings/core-upgrades/upload endpoint with only the settings.edit permission, allowing non-Superadmin administrators to upload and extract arbitrary zip archives over the live application source code. Attackers can upload a malicious archive containing modified application files such as routes/web.php with embedded system commands, which execute as the web server user with access to environment secrets and database credentials.

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.

No CAPEC attack patterns related to this CWE.
