Technical description

In Eclipse hawkBit versions 1.0.3 and prior, a privilege escalation vulnerability (CWE-284 / CWE-862) has been identified in the Direct Device Integration (DDI) Controller. This vulnerability allows an authenticated device to escalate its permissions and bypass the strict boundaries of its assigned updates. Under normal operation, a device should be restricted strictly to the specific firmware artifacts explicitly assigned to it. However, this flaw enables any authenticated device to bypass this restriction and download any firmware artifact within the same tenant. This is not an authentication bypass; the requesting device must possess valid credentials for its respective tenant. Instead, the issue stems from a flaw in object-level authorization validation. A related, lower-severity helper issue exists in the listing software modules artifacts metadata endpoint. This endpoint does not enforce assignment checks, enabling an authenticated device to list and enumerate available firmware artifacts, which can facilitate targeted exfiltration using the main download authorization bypass.

——9@fastify/static is a Fastify plugin that serves static files from a configured root directory. In versions before 10.1.4, on a case-insensitive filesystem such as Windows or the default macOS volume, a route guard or allowedPath restriction can be bypassed by altering the letter case of a path segment. The route matcher is case-sensitive while the filesystem is not, so a request that changes the case of a protected segment does not match the guarded route and falls through to the static handler, yet the filesystem resolves it to the same protected file. As a result, an unauthenticated request can read a file that a route guard or allowedPath was configured to protect. The issue does not affect case-sensitive filesystems and is not a directory traversal, since nothing is served from outside the configured root. The issue is fixed in @fastify/static 10.1.4, which validates the requested path against its actual on-disk spelling and rejects case-aliased paths before authorization. As a workaround, serve static files from a case-sensitive filesystem, or ensure route guards and allowedPath rules account for every letter-case variant of the protected paths.20h CVE-2026-615967.1 HIG

——5djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, djust's per-object authorization (`get_object` + `has_object_permission`, ADR-017) was enforced on the WebSocket mount and event paths but not on three other render entry points: (a) the initial HTTP GET render, (b) SPA `url_change` navigation, and (c) `{% live_render %}` embedded child views. An authenticated user could therefore view (and on some paths act on) an object they are not authorized for by loading the page directly, navigating to it via SPA url-change, or composing it as an embedded child — a classic IDOR / broken object-level access control on object-scoped views. This is fixed in djust 1.0.7. All render entry points now route through a shared `enforce_object_permission` chokepoint: HTTP GET returns 403, `url_change` emits a `permission_denied` frame and skips the render, and `{% live_render %}` (eager + lazy) refuses the embed. Views without a custom `get_object` are unaffected (no-op). No reliable workaround short of upgrading. Do not expose object-scoped views through the HTTP-GET / url_change / live_render paths until patched.1d
