Reachability Analysis
This vulnerability is potentially reachable
```
org.t246osslab.easybuggy.vulnerabilities.UnrestrictedSizeUploadServlet (Application)
-> ❌ org.apache.commons.io.FilenameUtils (Vulnerable Component)
```
Vulnerability Details
In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like "//../foo", or "\\..\foo", the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus "limited" path traversal), if the calling code would use the result to construct a path value.
:heavy_check_mark: This issue was automatically closed by Mend because the vulnerable library in the specific branch(es) was either marked as ignored or it is no longer part of the Mend inventory.
