|

|
|
<p>When creating and enabling a <code class="docutils literal notranslate"><span class="pre">command</span></code> engine on a public instance, you
|
|||
|
|
must be careful to avoid leaking private data.</p>
|
|||
|
|
</div>
|
|||
|
|
<p>The easiest solution is to limit the access by setting <code class="docutils literal notranslate"><span class="pre">tokens</span></code> as described
|
|||
|
|
in section <a class="reference internal" href="../../../admin/settings/settings_engine.html#private-engines"><span class="std std-ref">Private Engines (tokens)</span></a>. The engine base is flexible. Only your
|
|||
|
|
imagination can limit the power of this engine (and maybe security concerns).</p>
