php is vulnerable to cross-site scripting (XSS). It was discovered that PHPâs htmlspecialchars() function did not properly recognize partial multi-byte sequences for some multi-byte encodings, sending them to output without them being escaped. An attacker could use this flaw to perform a cross-site scripting attack.
