The North Korea-linked threat actor known as Moonstone Sleet has continued to push malicious npm packages to the JavaScript package registry with the aim of infecting Windows systems, underscoring the persistent nature of their campaigns. The packages in question, harthat-api and harthat-hash, were published on July 7, 2024, according to Datadog Security Labs. Both the libraries did not attract

Flowise is a drag & drop user interface to build a customized large language model flow. In version 1.4.3 of Flowise, a reflected cross-site scripting vulnerability occurs in the `/api/v1/chatflows-streaming/id` endpoint. If the default configuration is used (unauthenticated), an attacker may be able to craft a specially crafted URL that injects Javascript into the user sessions, allowing the attacker to steal information, create false popups, or even redirect the user to other websites without interaction. If the chatflow ID is not found, its value is reflected in the 404 page, which has type text/html. This allows an attacker to attach arbitrary scripts to the page, allowing an attacker to steal sensitive information. This XSS may be chained with the path injection to allow an attacker without direct access to Flowise to read arbitrary files from the Flowise server. As of time of publication, no known patches are available.

NextChat, also known as ChatGPT-Next-Web, is a cross-platform chat user interface for use with ChatGPT. Versions 2.11.2 and prior are vulnerable to server-side request forgery and cross-site scripting. This vulnerability enables read access to internal HTTP endpoints but also write access using HTTP POST, PUT, and other methods. Attackers can also use this vulnerability to mask their source IP by forwarding malicious traffic intended for other Internet targets through these open proxies. As of time of publication, no patch is available, but other mitigation strategies are available. Users may avoid exposing the application to the public internet or, if exposing the application to the internet, ensure it is an isolated network with no access to any other internal resources.

### Summary Due to the insufficient validation of the `path` parameter in the NuxtTestComponentWrapper, an attacker can execute arbitrary JavaScript on the server side, which allows them to execute arbitrary commands. ### Details While running the test, a special component named `NuxtTestComponentWrapper` is available. https://github.com/nuxt/nuxt/blob/4779f5906fa4d3c784c2e2d6fe5a5c5f181faaec/packages/nuxt/src/app/components/nuxt-root.vue#L42-L43 This component loads the specified path as a component and renders it. https://github.com/nuxt/nuxt/blob/4779f5906fa4d3c784c2e2d6fe5a5c5f181faaec/packages/nuxt/src/app/components/test-component-wrapper.ts#L9-L27 There is a validation for the `path` parameter to check whether the path traversal is performed, but this check is not sufficient. https://github.com/nuxt/nuxt/blob/4779f5906fa4d3c784c2e2d6fe5a5c5f181faaec/packages/nuxt/src/app/components/test-component-wrapper.ts#L15-L19 Since `import(...)` uses `query.path` instead of the norma...

### Summary Nuxt Devtools is missing authentication on the `getTextAssetContent` RPC function which is vulnerable to path traversal. Combined with a lack of Origin checks on the WebSocket handler, an attacker is able to interact with a locally running devtools instance and exfiltrate data abusing this vulnerability. In certain configurations an attacker could leak the devtools authentication token and then abuse other RPC functions to achieve RCE. ### Details The `getTextAssetContent` function does not check for path traversals [(source)](https://github.com/nuxt/devtools/blob/c4f2b68281203fc3f61ffc97d9c6623fbfde46bb/packages/devtools/src/server-rpc/assets.ts#L88C48-L88C48), this could allow an attacker to read arbitrary files over the RPC WebSocket. The WebSocket server does not check the origin of the request [(source)](https://github.com/nuxt/devtools/blob/c4f2b68281203fc3f61ffc97d9c6623fbfde46bb/packages/devtools/src/server-rpc/index.ts#L109) leading to [CSWSH](https://ports...

In the Elliptic package 6.5.6 for Node.js, EDDSA signature malleability occurs because there is a missing signature length check, and thus zero-valued bytes can be removed or appended.
