In the following example, an XSS neutralization method replaces script tags in user supplied input with a safe equivalent:
}return input.replaceAll("script", mask);
The code only works when the "script" tag is in all lower-case, forming an incomplete blacklist (CWE-184). Equivalent tags such as "SCRIPT" or "ScRiPt" will not be neutralized by this method, allowing an XSS attack.
