Stored XSS via unchecked template import
Published Sep 12, 2026 · Updated Sep 12, 2026
Stored XSS in Export & Import WPBakery Page Builder 1.0.2 and earlier allows attackers to execute script via a forged template import. The template-import handler performs no CSRF validation, then stores and echoes imported data without sanitization or output escaping. Successful exploitation requires a logged-in administrator to submit the forged request, after which the stored script runs with that administrator's browser privileges.
