            *!!!WARNING!!!*
            `nosec` detected in the following files: ${{ env.nosec_files }}

            Be very careful about using `#nosec` in code. It can be a quick way to suppress security warnings and move forward with development, it should be employed with caution. Suppressing warnings with #nosec can hide potentially serious vulnerabilities. Only use #nosec when you're absolutely certain that the security issue is either a false positive or has been mitigated in another way.

            Only suppress a single rule (or a specific set of rules) within a section of code, while continuing to scan for other problems. To do this, you can list the rule(s) to be suppressed within the #nosec annotation, e.g: /* #nosec G401 */ or //#nosec G201 G202 G203
            Broad `#nosec` annotations should be avoided, as they can hide other vulnerabilities. **The CI will block you from merging this PR until you remove `#nosec` annotations that do not target specific rules**.

            Pay extra attention to the way `#nosec` is being used in the files listed above.
