This issue exists in the file include/class.admin.locations.add.php and is caused due to the lack of output encoding on the start request parameter.

$this->section_params['opening_html'] =
"<form id='manualAddForm' name='manualAddForm' method='post'>" .
( $this->adding ? '<input type="hidden" id="act" name="act" value="add" />' : '<input type="hidden" id="act" name="act" value="edit" />' ) .
"<input type='hidden' name='id' " .
"id='id' value='{$this->slplus->currentLocation->id}' />" .
"<input type='hidden' name='locationID' " .
"id='locationID' value='{$this->slplus->currentLocation->id}' />" .
"<input type='hidden' name='linked_postid-{$this->slplus->currentLocation->id}' " .
"id='linked_postid-{$this->slplus->currentLocation->id}' value='" .
$this->slplus->currentLocation->linked_postid .
"' />" .
( isset( $_REQUEST['start'] ) ? "<input type='hidden' name='start' id='start' value='{$_REQUEST['start']}' />" : '' ) .
"<a name='a{$this->slplus->currentLocation->id}'></a>";



In order to exploit this issue, the attacker has to lure/force a logged on WordPress Administrator into opening a malicious website.
