The FluentCart A New Era of eCommerce WordPress plugin before 1.4.0 does not verify that a subscription belongs to the requesting customer in several of its payment-method endpoints, allowing any authenticated customer to act on another customer's subscription (changing its payment method, or cancelling and re-binding it) when they know the target subscription identifier.

An access control vulnerability in the mobile app (APK v5.5.0) for Ghost Robotics' Vision 60 robot allows multiple simultaneous sessions to run without proper client validation or session integrity checks. An attacker with a modified version of the app can connect to the robot during an active, legitimate session. This allows the attacker to bypass control restrictions, intercept sensitive information (such as real-time video), and partially interact with the system unnoticed and without disconnecting the legitimate user, compromising confidentiality and operational security.

The Download Manager WordPress plugin before 3.3.62 does not bind its temporary download token to the requesting session nor expire it promptly, making the token a long-lived, multi-use, portable bearer token, so that an attacker who obtains one leaked download key can repeatedly download a role- or password-protected package file without authorization.

Improper access control in Azure App Service allows an unauthorized attacker to elevate privileges over a network.

In Eclipse BaSyx Go Components versions up to and including 1.0.0, ABAC-enabled deployments are vulnerable to an authorization bypass caused by inconsistent trailing-slash handling between the ABAC middleware and the HTTP router. The shared router configuration used Chi's `middleware.StripSlashes`, so a request such as `GET /shells/` was dispatched to the registered `GET /shells` route. However, the ABAC middleware evaluated the original request path including the trailing slash. If ABAC route lookup did not find a matching slash-suffixed route, the request was passed onward and the router then stripped the slash and executed the protected handler without the intended ABAC authorization decision and without the expected ABAC query filters. An unauthenticated or unauthorized network attacker could append a trailing slash to protected API routes to reach handlers that should have been denied by ABAC policy. Depending on the exposed component, HTTP method, and deployed policy, this could allow unauthorized read, create, update, delete, or upload operations. The issue affects ABAC-enabled deployments of services that use the shared router and ABAC middleware, including AAS Repository, Submodel Repository, AAS Registry, Submodel Registry, Concept Description Repository, Discovery, AAS Environment upload, and related services. The issue is fixed in Eclipse BaSyx Go Components v1.0.1.

The WowOptin: Next-Gen Popup Maker WordPress plugin before 1.4.38 does not have proper authorization on a REST endpoint, allowing unauthenticated users to disable all of the site's opt-in forms and insert new template-based opt-in rows into the database.
