From 1.0.0-alpha1 until 1.2.3, PHPCSUtils\\AbstractSniffs\\AbstractArrayDeclarationSniff::getActualArrayKey() evaluates attacker-controlled array-key expressions with eval(), allowing callback-form keys in untrusted PHP code scanned by an extending sniff to execute arbitrary commands on the scanning host.
