Applications may contain vulnerabilities to attack via malicious inputs. Machine-learning models may be trained to detect these vulnerabilities by accepting source code as input and outputting a probability that each of a set of vulnerabilities exists in the source code. Explanation methods may identify one or more locations within the source code that are likely to cause the vulnerability. Directed fuzzing provides a range of inputs to source code. The inputs that cause the source code to fail are detected and the portions of the source code that were vulnerable are identified. The results of the directed fuzzing are used to select between explanations generated by multiple explanation methods, to provide additional training data to a machine-learning model, to provide additional training data to an explanation method, or any suitable combination thereof.
