CVE-2024-31231Known exploitationNetwork attack vector

Unauthenticated PHP file inclusion via template traversal

Published May 17, 2024 · Updated Apr 28, 2026

Path traversal in Sizam Design REHub Theme 19.6.1 and earlier allows remote attackers to include local PHP files through a public AJAX action. The ajax_action_re_filterpost handler applies sanitize_text_field to the template POST parameter, then passes the resulting path through rh_locate_template to include without blocking traversal sequences. Unauthenticated access to wp_ajax_nopriv_re_filterpost is sufficient; included PHP can disclose output or execute code when attackers can influence its contents.
