🔒 [security fix] Replace document.write with appendChild in agreement/index.html#28
Conversation
…html Replaces the use of document.write and innerHTML for meta tag injection with a safer DOM manipulation method. This addresses a security vulnerability where dynamic content was being written to the document using risky methods. The new implementation uses (doc.head || docEl).appendChild(metaEl), ensuring reliable and safe tag placement. Co-authored-by: sunnylqm <615282+sunnylqm@users.noreply.github.com>

🎯 What: The vulnerability fixed was the use of
⚠️ Risk: Using
document.writewithinnerHTMLto dynamically inject a<meta>viewport tag inagreement/index.html.document.writeandinnerHTMLcan introduce security risks such as DOM-based XSS if the data being written is ever compromised or untrusted. It is also a deprecated practice in modern web development.🛡️ Solution: The fix replaces the risky logic with a standard and safe DOM manipulation:
(doc.head || docEl).appendChild(metaEl);. This ensures the meta tag is correctly appended to the document's head (or document element as a fallback) without the risks associated withdocument.write. Verified through visual inspection and automated DOM checks.PR created automatically by Jules for task 18078899721647218021 started by @sunnylqm
