The latest published release line is supported for security fixes and critical correctness issues.

If you believe you found a security issue in Veeam Designer:

1. Do not open a public issue with exploit details.
2. Email the maintainer or use the repository security advisory flow on GitHub.
3. Include the affected version, reproduction details, and any relevant logs or payloads.

You can expect an acknowledgement within a reasonable time and a coordinated fix or mitigation plan for confirmed issues.
