WebThe taint is introduced for all keyboard input values. A simple propagation rule of the tainting tool is the following: when a tainted value is stored in a register and moved to another register, the taint is propagated to the destination register and the corresponding instruction is added to the execution trace. WebContext propagation solves this issue. This handy mechanism has two parts. The context object passes these values around within your service, and the propagators pass the values to the next service whenever there is a network call. Having access to these values at any point in the transaction is what makes distributed tracing work. Context You are using input from the client/user (namly in the variable location) to construct an URL. So if the client/user supplies an malicious value to location he could form an invalid URL. In the second example String url = apiUrl + "location"; you are not using user input, as "location" is a hard coded String. lnwr 0-8-4t
