This issue was reported by CodeQL, IMHOI the alert was over reacting because contents was already extracted in a separate directory (which is absent in tree, so there is no risk to override) An extra check would be to verify a signed asset (using GPG), along a ZWA public key shared in tree.

Potential fix for https://github.com/rzr/z-wave-protocol-controller/security/code-scanning/7
To fix the issue, we need to check the return value of each
snprintfcall to ensure it is within the bounds of the remaining buffer size. If the return value is negative (indicating an encoding error) or exceeds the remaining buffer size, we should stop further writes to the buffer to prevent overflows. This involves modifying allsnprintfcalls in the affected functions (zwapi_demo_application_handlerandzwapi_demo_application_controller_update) to include these checks.Suggested fixes powered by Copilot Autofix.
