CWE: CWE-400 \u2014 Uncontrolled Resource Consumption
The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

Code:
function(d,f){if(Graph.isPageLink(f)){var g=d[f.substring(f.indexOf(",")+1)];f=null!=g?"data:page/id,"+g:null}else if("data:action/json,"==f.substring(0,17))try{var m=JSON.parse(f.substring(17));if(null!=m.actions){for(var q=0;q<m.actions.length;q++){var y=m.actions[q];if(null!=y.open&&Graph.isPageLink(y.open)){var F=y.open.substring(y.open.indexOf(",")+1);g=d[F];null!=g?y.open="data:page/id,"+g:null==this.getPageById(F)&&delete y.open}}f="data:action/json,"+JSON.stringify(m)}}catch(C){}return f};
