NodeBB Forum Software is powered by Node.js and supports either Redis, MongoDB, or a PostgreSQL database. It utilizes web sockets for instant interactions and real-time notifications. `utils.generateUUID`, a helper function available in essentially all versions of NodeBB (as far back as v1.0.1 and potentially earlier) used a cryptographically insecure Pseudo-random number generator (`Math.random()`), which meant that a specially crafted script combined with multiple invocations of the password reset functionality could enable an attacker to correctly calculate the reset code for an account they do not have access to. This vulnerability impacts all installations of NodeBB. The vulnerability allows for an attacker to take over any account without the involvement of the victim, and as such, the remediation should be applied immediately (either via NodeBB upgrade or cherry-pick of the specific changeset. The vulnerability has been patched in version 2.x and 1.19.x. There is no known workaround, but the patch sets listed above will fully patch the vulnerability.

undici is an HTTP/1.1 client, written from scratch for Node.js.`=< undici@5.8.0` users are vulnerable to _CRLF Injection_ on headers when using unsanitized input as request headers, more specifically, inside the `content-type` header. Example: ``` import { request } from 'undici' const unsanitizedContentTypeInput = 'application/json\r\n\r\nGET /foo2 HTTP/1.1' await request('http://localhost:3000, { method: 'GET', headers: { 'content-type': unsanitizedContentTypeInput }, }) ``` The above snippet will perform two requests in a single `request` API call: 1) `http://localhost:3000/` 2) `http://localhost:3000/foo2` This issue was patched in Undici v5.8.1. Sanitize input when sending content-type headers using user input as a workaround.

undici is an HTTP/1.1 client, written from scratch for Node.js.`undici` is vulnerable to SSRF (Server-side Request Forgery) when an application takes in **user input** into the `path/pathname` option of `undici.request`. If a user specifies a URL such as `http://127.0.0.1` or `//127.0.0.1` ```js const undici = require("undici") undici.request({origin: "http://example.com", pathname: "//127.0.0.1"}) ``` Instead of processing the request as `http://example.org//127.0.0.1` (or `http://example.org/http://127.0.0.1` when `http://127.0.0.1 is used`), it actually processes the request as `http://127.0.0.1/` and sends it to `http://127.0.0.1`. If a developer passes in user input into `path` parameter of `undici.request`, it can result in an _SSRF_ as they will assume that the hostname cannot change, when in actual fact it can change because the specified path parameter is combined with the base URL. This issue was fixed in `undici@5.8.1`. The best workaround is to validate user input before passing it to the `undici.request` call.

fs2 is a compositional, streaming I/O library for Scala. When establishing a server-mode `TLSSocket` using `fs2-io` on Node.js, the parameter `requestCert = true` is ignored, peer certificate verification is skipped, and the connection proceeds. The vulnerability is limited to: 1. `fs2-io` running on Node.js. The JVM TLS implementation is completely independent. 2. `TLSSocket`s in server-mode. Client-mode `TLSSocket`s are implemented via a different API. 3. mTLS as enabled via `requestCert = true` in `TLSParameters`. The default setting is `false` for server-mode `TLSSocket`s. It was introduced with the initial Node.js implementation of fs2-io in 3.1.0. A patch is released in v3.2.11. The requestCert = true parameter is respected and the peer certificate is verified. If verification fails, a SSLException is raised. If using an unpatched version on Node.js, do not use a server-mode TLSSocket with requestCert = true to establish a mTLS connection.

An issue was discovered in the file-type package before 16.5.4 and 17.x before 17.1.3 for Node.js. A malformed MKV file could cause the file type detector to get caught in an infinite loop. This would make the application become unresponsive and could be used to cause a DoS attack.

undici is an HTTP/1.1 client, written from scratch for Node.js. It is possible to inject CRLF sequences into request headers in undici in versions less than 5.7.1. A fix was released in version 5.8.0. Sanitizing all HTTP headers from untrusted sources to eliminate `\r\n` is a workaround for this issue.

Node.js is vulnerable to Hijack Execution Flow: DLL Hijacking under certain conditions on Windows platforms.This vulnerability can be exploited if the victim has the following dependencies on a Windows machine:* OpenSSL has been installed and “C:\Program Files\Common Files\SSL\openssl.cnf” exists.Whenever the above conditions are present, `node.exe` will search for `providers.dll` in the current user directory.After that, `node.exe` will try to search for `providers.dll` by the DLL Search Order in Windows.It is possible for an attacker to place the malicious file `providers.dll` under a variety of paths and exploit this vulnerability.

A cryptographic vulnerability exists on Node.js on linux in versions of 18.x prior to 18.40.0 which allowed a default path for openssl.cnf that might be accessible under some circumstances to a non-admin user instead of /etc/ssl as was the case in versions prior to the upgrade to OpenSSL 3.

The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly handle multi-line Transfer-Encoding headers. This can lead to HTTP Request Smuggling (HRS).

The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS).

The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly parse and validate Transfer-Encoding headers and can lead to HTTP Request Smuggling (HRS).

A OS Command Injection vulnerability exists in Node.js versions <14.20.0, <16.20.0, <18.5.0 due to an insufficient IsAllowedHost check that can easily be bypassed because IsIPAddress does not properly check if an IP address is invalid before making DBS requests allowing rebinding attacks.

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. In affected versions parse Server LiveQuery does not remove protected fields in classes, passing them to the client. The LiveQueryController now removes protected fields from the client response. Users are advised to upgrade. Users unable t upgrade should use `Parse.Cloud.afterLiveQueryEvent` to manually remove protected fields.

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. In affected versions certain types of invalid files requests are not handled properly and can crash the server. If you are running multiple Parse Server instances in a cluster, the availability impact may be low; if you are running Parse Server as single instance without redundancy, the availability impact may be high. This issue has been addressed in versions 4.10.12 and 5.2.3. Users are advised to upgrade. There are no known workarounds for this issue.

The got package before 12.1.0 (also fixed in 11.8.5) for Node.js allows a redirect to a UNIX socket.

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 4.10.11 and 5.2.2, the certificate in the Parse Server Apple Game Center auth adapter not validated. As a result, authentication could potentially be bypassed by making a fake certificate accessible via certain Apple domains and providing the URL to that certificate in an authData object. Versions 4.0.11 and 5.2.2 prevent this by introducing a new `rootCertificateUrl` property to the Parse Server Apple Game Center auth adapter which takes the URL to the root certificate of Apple's Game Center authentication certificate. If no value is set, the `rootCertificateUrl` property defaults to the URL of the current root certificate as of May 27, 2022. Keep in mind that the root certificate can change at any time and that it is the developer's responsibility to keep the root certificate URL up-to-date when using the Parse Server Apple Game Center auth adapter. There are no known workarounds for this issue.

Electron is a framework for writing cross-platform desktop applications using JavaScript (JS), HTML, and CSS. A vulnerability in versions prior to 18.0.0-beta.6, 17.2.0, 16.2.6, and 15.5.5 allows a renderer with JS execution to obtain access to a new renderer process with `nodeIntegrationInSubFrames` enabled which in turn allows effective access to `ipcRenderer`. The `nodeIntegrationInSubFrames` option does not implicitly grant Node.js access. Rather, it depends on the existing sandbox setting. If an application is sandboxed, then `nodeIntegrationInSubFrames` just gives access to the sandboxed renderer APIs, which include `ipcRenderer`. If the application then additionally exposes IPC messages without IPC `senderFrame` validation that perform privileged actions or return confidential data this access to `ipcRenderer` can in turn compromise your application / user even with the sandbox enabled. Electron versions 18.0.0-beta.6, 17.2.0, 16.2.6, and 15.5.5 contain a fix for this issue. As a workaround, ensure that all IPC message handlers appropriately validate `senderFrame`.

npm pack ignores root-level .gitignore and .npmignore file exclusion directives when run in a workspace or with a workspace flag (ie. `--workspaces`, `--workspace=<name>`). Anyone who has run `npm pack` or `npm publish` inside a workspace, as of v7.9.0 and v7.13.0 respectively, may be affected and have published files into the npm registry they did not intend to include. Users should upgrade to the latest, patched version of npm v8.11.0, run: npm i -g npm@latest . Node.js versions v16.15.1, v17.19.1, and v18.3.0 include the patched v8.11.0 version of npm.

OS command injection vulnerability in Turistforeningen node-s3-uploader through 2.0.3 for Node.js allows attackers to execute arbitrary commands via the metadata() function.

Google-it is a Node.js package which allows its users to send search queries to Google and receive the results in a JSON format. When using the 'Open in browser' option in versions up to 1.6.2, google-it will unsafely concat the result's link retrieved from google to a shell command, potentially exposing the server to RCE.
