Security Fix: Proper String Escaping in Regex and Query Handling

Summary

This PR addresses incomplete string escaping vulnerabilities identified by CodeQL in our JavaScript codebase.

Changes Made

• Query Parameter Handling

  • Updated rtmediaGetParameterByName() and related functions to properly escape [ and ] in parameter names.
  • Changed single-occurrence regex replacements (/[\[]/) to global replacements (/\[/g), ensuring all instances are safely escaped.

• Regex Escaping

  • Enhanced regex key escaping to also handle backslashes (\) in addition to ., +, and *.
  • Added inline comments explaining why escaping is necessary for regex safety and maintainability.

Why This Fix?

• Previous implementations only escaped the first instance of [ or ], leaving room for bypasses.
• Regex input escaping did not cover backslashes, potentially enabling malformed regex patterns.
• These gaps could allow query string manipulation or regex injection leading to unexpected behavior.

Impact

• Prevents potential XSS vectors or regex parsing issues.
• No functional changes for end users; all behavior remains intact.
