Internationalization introduces several security concerns primarily due to the complexity of handling diverse character sets and linguistic rules. A major issue involves input validation and encoding, where improper processing of Unicode characters can lead to vulnerabilities like SQL injection or Cross-Site Scripting (XSS) if malicious payloads bypass filters. Additionally, canonicalization issues arise when different representations of the same string are not handled consistently, potentially allowing attackers to evade security checks. Concerns also include path traversal vulnerabilities, where locale-specific file system interpretations can expose unauthorized directories, and locale-dependent logic flaws affecting sorting or comparison functions. Therefore, robust internationalization requires meticulous attention to secure coding practices and thorough testing across all supported locales to prevent exploitation.
