            <title>[SERVER-72292] Regex bug in dropDatabase in Sharded cluster </title>

                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We found in recent server build, the `dropDatabase` command failed with confusing errors&lt;/p&gt;

&lt;p/&gt;
&lt;p&gt;After a &lt;a href=&quot;https://mongodb.slack.com/archives/CKABWR2CT/p1671563138368729&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;discussion&lt;/a&gt; with &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=arun.banala%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;arun.banala@mongodb.com&quot;&gt;arun.banala@mongodb.com&lt;/a&gt; , we found the problem was introduced in this commit &lt;a href=&quot;https://github.com/mongodb/mongo/commit/fd2dd311397aa3671e69ae4e4d98056e8006620f&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/commit/fd2dd311397aa3671e69ae4e4d98056e8006620f&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;In the commit, it seems the special characters inside the database name weren&apos;t escaped when constructing a regex to match the other databases.&#160;&lt;/p&gt;

&lt;p&gt;Please prioritize the fix for this issue otherwise we will not be able to drop the database with special characters in a sharding cluster. Thx.&#160;&lt;/p&gt;</description>
