Stack-based buffer overflow and missing authorization vulnerability in Thales Sentinel Keys Server on Windows allows Overflow Buffers. Sentinel Keys Server does not check the length of the first field in the HTTP request. An attacker may craft an HTTP request and send it to Sentinel Keys Server. It may lead to remote code execution as NT AUTHORITY\SYSTEM. This issue affects Sentinel Keys Server: versions lower than 1.3.8.0.

CVE-2026-551476.3 MED—
———LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. In versions from 22.0.0 prior to 27.0.4 and from 28.0.0 prior to 28.0.2, the `API` for the `imaging_browser` module permits edits to imaging data without checking the frontend permissions that restrict editing in Imaging Browser. An authenticated `API` caller can therefore modify imaging data without the required edit authorization. Deployments that no longer use the `API` can disable it to remove access to this endpoint. This issue is fixed in versions 27.0.4 and 28.0.2.3hCVE-2026-551464.3 MED—
———LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. In versions from 16.0.0 prior to 27.0.4 and from 28.0.0 prior to 28.0.2, the `issue_tracker` backend does not correctly verify edit access permissions, although the frontend restricts which issues a user may edit. An authenticated user can submit backend changes to issues outside the user's permitted edit scope. Deployments that no longer use Issue Tracker can disable the module to remove access to the endpoint. This issue is fixed in versions 27.0.4 and 28.0.2.3hCVE-2026-629898.1 ALT—
———Shopper is a Headless e-commerce Admin Panel. Prior to 2.10.0, the Variants Livewire component in `packages/admin/src/Livewire/Components/Products/Form/Variants.php` exposes `DeleteAction` and `DeleteBulkAction` without server-side authorization. An authenticated staff user with `edit_products` can access `/shopper/products/{id}/edit` and obtain the signed component state even without `delete_product_variants`. The `callTableAction` and `callTableBulkAction` paths then permanently delete individual or multiple variants without checking that dedicated permission. For variant products, this can destroy the sellable catalogue and disrupt storefront product pages, cart, and checkout. This issue is fixed in version 2.10.0.4hCVE-2026-629678.1 ALT—
———ZTNET is a ZeroTier web UI for private controllers with multiuser and organization support. Prior to 0.8.0, any authenticated low-privilege user can permanently deactivate another account, including an administrator, through `POST /api/auth/user/invalidateUser`. In `src/pages/api/auth/user/invalidateUser.ts`, `getServerSession` checks only that a session exists and does not compare `session.user.id` with the client-supplied `userId`. Supplying a victim's `userId` and a `deviceId` for which no matching pair exists in `UserDevice` makes the handler set the target account's `isActive` to false. Login is then refused by `src/server/auth.ts` with `account-expired`. An attacker needs only a normal authenticated account and the victim's user ID, which may be obtainable from member lists, UI responses, logs, or other application metadata. This can lock administrators out, disrupt organization management, and deny access to any targeted user. This issue is fixed in version 0.8.0.4hCVE-2026-784027.8 ALT—
———Stack-based buffer overflow and out-of-bounds
write vulnerability in Thales Sentinel Keys Server on Windows allows Overflow
Buffers.
Sentinel Keys Server does not check the length of the first field in
the input message. A local attacker may craft an input and send it to Sentinel
Keys Server. It may lead to code execution as NT AUTHORITY\SYSTEM enabling
local privilege escalation.

———MyTube is a self-hosted downloader and player for several video websites. Prior to version 1.10.3, backend video access does not enforce the visitor role's intended public-only restriction when `loginEnabled=true` and a visitor password is configured. The frontend filter in `VideoContext.tsx` is only client-side, `roleBasedAuthMiddleware.ts` allows all visitor GET requests, and `storageService/videos.ts` performs `getVideos()` and `getVideoById(id)` queries without checking the caller's role or `visibility`. A visitor can enumerate `/api/videos` or request `/api/videos/:id` to retrieve hidden `visibility`=0 records, exposing titles, `sourceUrl` values, `videoPath` values, subtitle paths and `thumbnailPath` values. The `serveMountVideo()` path also serves mounted video files without `visibility` checks. Leaked paths work against unauthenticated `/videos/*` and `/subtitles/*` routes, allowing media downloads without credentials. The RSS visitor feed already filters `visibility`=1 content and is not the affected query path. Default loginEnabled=false single-user deployments are unaffected by this role-boundary issue because all callers are owner-equivalent. This issue is fixed in version 1.10.3.5h
