Affected packages
• Maven com.netflix.priam:priam: <= 3.1.104 (no fix yet)
Description
Impact
When `File.createTempFile` creates a file, the permissions on that file are -rw-r--r--. This means that other users can read the contents of these files after they are written, although they can not modify the contents. This allows for local information disclosure if these files contain sensitive information.
