What is CVE-2025-44136?

MapTiler Tileserver-php version 2.0 is susceptible to a Cross Site Scripting (XSS) vulnerability. The issue arises from the improper handling of the 'layer' GET parameter, which is reflected in error messages without proper HTML encoding. This oversight allows unauthenticated attackers to execute arbitrary HTML or JavaScript code in the context of a user's browser, potentially leading to data theft or session hijacking. It is imperative for users of this version to apply security measures to mitigate potential risks.
