#58017 new defect (bug)

Exception thrown when using array-data in URL query

Reported by: saemideluxe's profile saemideluxe Owned by:

Severity: normal Version: 6.2

When using the following URL query:


Then the following function:

/wp-includes/blocks/navigation-link.php(129): block_core_navigation_link_maybe_urldecode

will throw the following Error:

Uncaught TypeError: rawurldecode(): Argument #1 ($string) must be of type string, array given

because the function wp_parse_args (that is used in the function above) will parse the given URL to return query-keys ending with []-characters to be an array and not a plain string, see output from print_r:


[mtype] => libraryitem
[maps-tag] => Array


[0] => children



But the function rawurldecode that is used below expects the argument to be a string, not an array.

This suddenly started happening, I assume after 6.2 got released on March 29, 2023.

On Wordpress 6.4 with PHP 8.2 the follwing URL goes into the function block_core_navigation_link_maybe_urldecode:

This will result in the mentioned exception.
