CVE-2026-68484—

—

———Cash Collect contains an improper authorization vulnerability in the Sage AR Automation API. Administrative functions do not properly verify user privileges, allowing authenticated low-privileged users to create administrator accounts and obtain elevated privileges.9h CVE-2026-867656.5 MED

—

———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}.11h CVE-2026-867646.5 MED

—

———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.11h CVE-2026-867628.1 HIG

—

———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.11h CVE-2026-867597.1 HIG

—

———Snipe-IT versions before 8.7.0 fail to authorize the POST /hardware/history endpoint, allowing any authenticated user to reassign arbitrary assets and modify audit logs. Attackers can submit a CSV file to reassign assets across companies and inject fraudulent audit trail entries, compromising inventory integrity and accountability.11h CVE-2026-867576.5 MED

—

———Snipe-IT before 8.7.0 fails to properly gate access to encrypted custom-field values in asset form templates for listbox, textarea, markdown-textarea, and date/datetime picker elements. Authenticated users with assets.edit, assets.checkin, assets.checkout, or assets.audit permissions can read plaintext encrypted custom field values by opening asset forms, bypassing the assets.view.encrypted_custom_fields permission check.11h
