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.

GHSA-q898-frwq-f3qp — Minecraft MOTD Parser's HtmlGenerator vulnerable to XSS

2026-10-08T11:30:39.928383+00:00

Affected: Packagist: dev-lancer/minecraft-motd-parser

### Summary The `HtmlGenerator` class is subject to potential cross-site scripting (XSS) attack through a parsed malformed Minecraft server MOTD.

### Context Minecraft server owners can set a so-called MOTD (Message of the Day) for their server that appears next to the server icon and below the server name on the multiplayer server list of a player's Minecraft client. The Minecraft server sends the MOTD in the `description` property of the [Status Response](https://wiki.vg/Server_List_Ping#Status_Response) packet. The [jgniecki/MinecraftMotdParser](https://github.com/jgniecki/MinecraftMotdParser) PHP library is able to parse the value of the `description` property, which can be either a string or an array of text components. By utilizing the aforementioned `HtmlGenerator` class, it is also able to transform the value into an HTML string that can be used to visualize the MOTD on a web page.

### Details 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, as can be seen here: - https://github.com/jgniec…
