Summary

Versions of the package nice-select2 before 2.4.1 are vulnerable to Cross-site Scripting (XSS) via the <select> element. An attacker can supply a malicious payload that is rendered directly into the DOM without proper sanitization, causing arbitrary script execution in a victim’s browser when they view or interact with the affected page.
