Submit #698115: nnn v5.1 Double Freeinfo

Titelnnn v5.1 Double Free
BeschreibungThe run_cmd_as_plugin function contains a double-free vulnerability when handling the F_WINDOW flag. The content buffer is passed to show_content_in_floating_window, which frees the memory if window creation fails. However, run_cmd_as_plugin unconditionally calls free(content) immediately after that function returns. This causes the memory to be freed a second time if an error occurs within the window display logic.
