            "package": {
                "name": "drupalcode/xss_prevention",
                "version": "3396472",
                "type": "drupal-module",
                "source": {
                    "type": "git",
                    "url": "https://git.drupalcode.org/issue/xss_prevention-3396472.git",
                    "reference": "4f6251796679a50ac7d1252dd312098313f09e9b"
                }
            }
        },

and under "require",
"drupalcode/xss_prevention": "3396472",

Then
composer update

I have the same error, we hope they fix it in the next update.

Tested #4 on Drupal 9.5 with 1.2 XSS Prevention modules and it's working.
