can lead to denial of service (bsc#1275461).</li>
<li>CVE-2026-59894: improper backlash escaping allows for injection of Python or PHP code via a crafted SQL input
(bsc#1275460).</li>
<li>CVE-2026-71491: quadratic complexity in <code>group_comments</code> when processing comment-only statements can lead to denial
of services (bsc#1275466).</li>
