# Duplicate Tainted Sources ![Tainted Sources to represent duplicate steps (refresh page to view from start)](https://73151925-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lgwbks2UGHSbePWCNz0%2F-LhGiqqCS4qKdQEqKlUL%2F-LhGwlqSQXDovz370JF3%2FTaintSourceHop.gif?alt=media\&token=da0bd5eb-fb49-4c1c-812b-2e01509bc438) Sboxr captures and displays every step involved in the journey of potentially untrusted data from the Source to the Sink that causes Code Evaluation. Sometimes the same data is used in multiple steps, in these cases to simplify the display of data Sboxr will group all such duplicate data into one **Tainted data**. An index is assigned to this Tainted Data and clicking on the Tainted data step will take you to another section of the page where all the details of the Tainted data are present. Tainted data are given an id, starting from 1. In complex cases you will find more than one Tainted data, so this id is used to differentiate them. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.sboxr.com/view-issues/code-execution-issues/duplicate-tainted-sources.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
