Unicode Transformation Issue

Impact: High


The Unicode Standard provides a unified encoding scheme for characters worldwide, enhancing program globalization and security. However, improper usage of Unicode can introduce security vulnerabilities, including visual security issues, UTF-8 exploits, text comparison vulnerabilities, buffer overflows, and code point deletions. Hackers exploit these vulnerabilities to bypass Web Application Firewalls (WAFs) and launch attacks such as XSS and SQL Injection.


Review all functions handling input to ensure adherence to Unicode security best practices outlined in the provided references. Keep libraries up to date to mitigate potential vulnerabilities.
