# Plugin supply chain

Plugin supply-chain risk is when trusted plugin code or updates become a path for attackers.

[Full guide](https://wpsecurityninja.com/how-to-tell-if-a-wordpress-plugin-is-secure/)

## Why it matters for WordPress

You inherit the security of every plugin author you install. Abandoned plugins, stolen publisher accounts, and pirated “nulled” packages keep showing up in incident reports. The update you clicked can be the delivery path.

## How it shows up in practice

- Advisories about a popular plugin’s distribution or maintainer account
- Nulled or “GPL club” zips that ship webshells beside the feature you wanted
- Plugins that phone home or pull remote code at runtime without a clear reason
- A critical CVE in a dependency you forgot was still active

## What to do

1. Install fewer plugins; remove what you do not use.
2. Prefer wordpress.org and known vendors. Never random null dumps.
3. Watch for odd new files right after an update.
4. Have a patch plan when a critical CVE hits something you depend on.
5. Prefer maintained plugins with a clear owner over abandoned one-offs.
