1. A computer-implemented system comprising: a processor configured to execute computer-executable instructions; and memory storing computer-executable instructions for: fuzzing, by a fuzzer, at least one valid uniform resource identifier body to generate a fuzzed uniform resource identifier body; appending a uniform resource identifier header to the fuzzed uniform resource identifier body to create a fuzzed uniform resource identifier; monitoring, by a debugger, a target application for effects of invocation of the fuzzed uniform resource identifier; and automatically outputting, by the debugger to the fuzzer, suggested fuzzing for one or more subsequent valid uniform resource identifier bodies based, at least, on monitored effects of the invocation of the fuzzed uniform resource identifier.
