An issue was discovered in phpMyAdmin before 4.8.5. When the AllowArbitraryServer configuration setting is set to true, with the use of a rogue MySQL server, an attacker can read any file on the server that the web server's user can access. This is related to the mysql.allow_local_infile PHP configuration, and the inadvertent ignoring of options(MYSQLI_OPT_LOCAL_INFILE calls. https://nvd.nist.gov/vuln/detail/CVE-2019-6799
