CVE-2022-29244low · fixedCVSS 3.1

Packing does not respect root-level ignore files in workspaces

### Impact `npm pack` ignores root-level `.gitignore` & `.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` with workspaces, as of [v7.9.0](https://github.com/npm/cli/releases/tag/v7.9.0) & [v7.13.0](https://github.com/npm/cli/releases/tag/v7.13.0) respectively, may be affected and have published files into the npm registry they did not intend to include. ### Patch - Up

CVE-2018-7408low · fixedCVSS 3

Incorrect Permission Assignment for Critical Resource in NPM

An issue was discovered in an npm 5.7.0 2018-02-21 pre-release (marked as "next: 5.7.0" and therefore automatically installed by an "npm upgrade -g npm" command, and also announced in the vendor's blog without mention of pre-release status). It might allow local users to bypass intended filesystem access restrictions because ownerships of /etc and /usr directories are being changed unexpectedly, related to a "correctMkdir" issue.

Affected: >= 0Fixed in 5.7.1source →

CVE-2013-4116info · fixed

Local Privilege Escalation in npm

Affected versions of `npm` use predictable temporary file names during archive unpacking. If an attacker can create a symbolic link at the location of one of these temporary file names, the attacker can arbitrarily write to any file that the user which owns the `npm` process has permission to write to, potentially resulting in local privilege escalation. ## Recommendation Update to version 1.3.3 or later.

CVE-2020-15095low · fixedCVSS 3.1

npm CLI exposing sensitive information through logs

Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like `<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>`. The password value is not redacted and is printed to stdout and also to any generated log files.

CVE-2019-16777low · fixedCVSS 3.1

npm Vulnerable to Global node_modules Binary Overwrite

Versions of the npm CLI prior to 6.13.4 are vulnerable to a Global node_modules Binary Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the first binary. This will not overwrite system binaries but only binaries put into the global node_modules directory. This b

World Weather Online — MCP Server (Railway)

MCP server for World Weather Online. Lets AI assistants like Claude, Cursor, and others call WWO weather data directly as tools.

Deploy to Railway

Step 1 — Push to GitHub

Create a new repository on github.com (call it wwo-mcp-server)
Open Terminal in this folder and run:

git init
git add .
git commit -m "Initial commit"
git remote add origin https://github.com/YOUR_USERNAME/wwo-mcp-server.git
git push -u origin main

Step 2 — Deploy on Railway

Go to https://railway.app and sign up / log in with GitHub
Click New Project → Deploy from GitHub repo
Select your wwo-mcp-server repository
Railway detects Node.js automatically and deploys

Your server will be live at a URL like:

https://wwo-mcp-server-production.up.railway.app

Step 3 — Add Custom Domain

In Railway dashboard → your project → Settings → Networking → Custom Domain
Type mcp.worldweatheronline.com and click Add

Railway shows you a CNAME value like:

wwo-mcp-server-production.up.railway.app

Go to your DNS provider and add:

Type Name Value
CNAME mcp wwo-mcp-server-production.up.railway.app
SSL certificate is provisioned automatically within minutes

Type	Name	Value
CNAME	mcp	wwo-mcp-server-production.up.railway.app

Step 4 — Test

Visit your health endpoint:

https://mcp.worldweatheronline.com/health

Test in MCP Inspector:

https://mcp.worldweatheronline.com/mcp?key=YOUR_WWO_API_KEY
