            <title>[SERVER-84175] PlanExecutor::getNext() is returning unowned BSON objects </title>
                <link>https://jira.mongodb.org/browse/SERVER-84175</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The changes introduced by &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-82970&quot; title=&quot;Remove cursor cache from server as WiredTiger already caches cursor&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-82970&quot;&gt;SERVER-82970&lt;/a&gt; exposed the fact that the &lt;tt&gt;PlanExecutor::getNext()&lt;/tt&gt; (or at least, the implementation defined by &lt;tt&gt;PlanExecutorImpl&lt;/tt&gt;) is returning unowned BSONObject to its callers, which may experience segmentation fault error in case the executor object gets destroyed before accessing such objects.&lt;/p&gt;

&lt;p&gt;This ticket proposes to either implement a more robust behaviour - or to make the limitation explicit through the documentation of the interface.&lt;/p&gt;</description>
