Potential fix for https://github.com/f1anderz/msg-parser/security/code-scanning/6
Найкращий практичний підхід — використовувати перевірену sanitizer-бібліотеку (наприклад DOMPurify), але в межах наданого фрагмента без додавання зовнішньої залежності треба мінімально й безпечно виправити regex, щоб він видаляв також “помилкові, але прийнятні браузером” варіанти закривального script-тега.
Оптимальна точкова правка в
reference/msg-preview.js(рядок з.replace(/<script\b[\s\S]*?<\/script\s*>/gi, '')):замінити шаблон на такий, що дозволяє будь-які символи, крім
>, міжscriptі>у закривальному тезі:</script\s*></script\b[^>]*>Це покриє
</script foo="bar">,</script\t\n bar>тощо, не змінюючи решту поведінки функції.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
