For a suspected security issue in DXF Viewer, email abysstailcrafts@gmail.com with the subject DXF Viewer security report. This is the project's published maintainer contact.

Include the application version, operating system, affected workflow, impact and minimal reproduction steps. Use a harmless sample; do not send credentials, private drawings or unrelated personal files. Please report sensitive details privately before publishing them.

Ordinary rendering bugs and feature requests belong in GitHub Issues.

Reports against the latest published release are most useful. Historical versions remain available for reference; there is no guaranteed response time or maintenance window for older releases. Open security-related work is tracked honestly and should not be interpreted as already fixed.
