1. A method for in-development vulnerability response management, comprising: detecting a code instance that matches a vulnerability pattern, the detecting done during a development stage of writing the code instance; generating, using a processor, one or more hints associated with the code instance in response to the detecting; providing the one or more hints on a user interface via which the code instance is being written; retrieving an action response to the code instance that matches a vulnerability pattern; and associating the retrieved action response with the code instance, wherein the one or more hints comprise one or more fixes in one or more sanitization locations, at least one of said one or more sanitization locations being in an execution flow of a previously stored sample code, and said one or more hints being adaptive hints that are based on context, wherein the one or more fixes are prioritized according to reputation of authors that created the one or more fixes, wherein the action response comprises performing said one or more fixes, to mitigate vulnerability of the code instance.
