In this instance, an attacker with local access to the machine can exploit this flaw to execute <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-58372-roo-code-vulnerability-leading-to-arbitrary-code-execution\/\"  data-wpil-monitor-id=\"87761\">arbitrary code<\/a> with elevated privileges.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2533980705\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Here&#8217;s a conceptual example of how this vulnerability might be exploited.
