<h2>Bug Fixes</h2>
<ul>
<li>
<p><a href="https://github-redirect.dependabot.com/pytest-dev/pytest/issues/8414">#8414</a>: pytest used to create directories under <code>/tmp</code> with world-readable
permissions. This means that any user in the system was able to read
information written by tests in temporary directories (such as those created by
the <code>tmp_path</code>/<code>tmpdir</code> fixture). Now the directories are created with
private permissions.</p>
<p>pytest used silenty use a pre-existing <code>/tmp/pytest-of-&lt;username&gt;</code> directory,
even if owned by another user. This means another user could pre-create such a
directory and gain control of another user's temporary directory. Now such a
condition results in an error.</p>
