PHP Warning: trim() expects parameter 1 to be string, array given

[Darko A7]

Hi,

I noticed few lines in my logs, not sure if generated warning is just on purpose, or missed check on php side:

access log:

31.145.214.139 - - [26/Jun/2020:00:09:26 +0200] "POST /mysql-root-?q=user%2Fpassword&name%5B%23post_render%5D%5B%5D=passthru&name%5B%23type%5D=markup&name%5B%23markup%5D=id HTTP/1.1" 200 17221

error log:

[Fri Jun 26 00:09:26.942439 2020] [:error] [pid 13725] [client 31.145.214.139:55140] PHP Warning:  trim() expects parameter 1 to be string, array given in /.../wp-includes/class-wp-query.php on line 777

code @ L777:

public function parse_query( $query = '' ) {

(...)

$qv['name']     = trim( $qv['name'] );
