Overview
Affected versions of this package are vulnerable to Information Exposure. On unix-like systems, the temporary directory is shared between all users. As such, writing to this directory using API's that do not explicitly set the file/directory permissions can lead to information disclosure.
When files/directories are created using the File.createTempFile
method, the default umask
settings for the process are respected. As a result, by default, most processes/apis will create files/directories with the permissions -rw-r--r--
and drwxr-xr-x
respectively, unless an API that explicitly sets safe file permissions is used.
