## Technical details

The vulnerability exists due to improper validation of symbolic links in FTM, allowing an authenticated remote attacker to access sensitive information through symlink traversal. An attacker must be authenticated to the system but can then traverse symbolic links to read files outside intended directories. The vulnerability affects FTM running on RedHat OpenShift environments.
