The most dangerous vulnerability (CVE-2026-23918) is caused by double memory release in the mod_http2 module and could potentially lead to remote code execution on the server through HTTP\/2 protocol manipulation. The vulnerability is only present in the 2.4.66 release. It has been assigned a severity level of 8.8 out of 10.    <\/p>\n<p>Another vulnerability (CVE-2026-24072) with a severity level of 8.8 exists in the mod_rewrite module and allows local users <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/\" title=\"hosting\" data-wpil-keyword-link=\"linked\">hosting<\/a>, having the ability to create files &#171;.htaccess&#187;, read the contents of any files in the system with the privileges of the user under which the httpd process is running.        <\/p>\n<p>Less critical vulnerabilities:  <\/p>\n<ul>\n<li class=\"l\"> CVE-2026-28780 \u2014 a buffer overflow in mod_proxy_ajp, which can be exploited when connecting the proxy to a malicious AJP server.

between the frontend and backend.\n<li class=\"l\"> CVE-2026-33006 \u2014 an attack via side channels (timing analysis) on mod_auth_digest, allowing bypassing of Digest authentication.\n<li
