Describe the Task

After ugrading to SonarQube v2025.3.1, the categories of SonarQube findings have changed slightly. Security issues (previously called Vulnerability) must be zero for each release.

As of Oct 8, 2025, METviewers's develop branch contains 10 Security, 18 Reliability, and 1,284 Maintainability issues. This task is to address and resolve the 10 Security issues from METviewer's develop branch.
