What do the columns represent?

The 1st column in the table indicates the method in this repository that was found to be affected
by vulnerable methods from the jackson-databind package.

The 2nd column indicates the jackson-databind method that was directly called from this repository.

The 3rd column indicates the origin vulnerable method in the jackson-databind package. According to our dataset, this is one of the methods that produces the CVE-2019-14379 vulnerability. This method was found to be internally chain-called in the jackson-databind package by the method listed in column 2.

How were the results generated?

This vulnerability was analyzed specifically for usage in this project using the FASTEN Project. Statical method-level analysis was used to check for usage of vulnerable methods in the project.

Method calls between your project and jackson-databind have been mapped using a directed graph. From this graph, it could be then be seen whether any vulnerable jackson-databind methods are being called from within your project.
