TL;DR

This module adds autocomplete suggestions for Search API search forms. It ships with a test script that is accessible to anonymous users and does not sufficiently validate user input, leading to cross-site scripting. Exploitation is mitigated when the web server is not configured to display PHP warning messages to users.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and your PHP or web server configuration displays warning messages to users (for example, with display_errors enabled).

Background info

drupal/search_api_autocomplete is vulnerable to Cross-Site Scripting (XSS) in versions 0.0.1 - 1.11.0.

How to fix this

Upgrade the drupal/search_api_autocomplete module to the patch version. If you cannot update immediately, set display_errors: off in php.ini or equivalent settings.
