This function fails to properly sanitize user-supplied input during property assignment operations.

This is known as prototype pollution.<br \/>\nIf the polluted properties are later accessed or executed, it could lead to <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-30256-denial-of-service-vulnerability-in-tenda-ac6-s-http-header-parsing-functionality\/\"  data-wpil-monitor-id=\"86851\">denial of service<\/a> conditions, unexpected application behavior, or potential execution of arbitrary code.
