CVE-2026-73033: Path traversal vulnerability

Sucuri Security WordPress plugin through version 2.7.3 contains a path traversal vulnerability in the pageIntegritySubmission() method in src/integrity.lib.php that allows authenticated administrators to delete arbitrary files by supplying directory traversal sequences in the sucuriscan_integrity parameter. Attackers can manipulate the unsanitized file path concatenated with ABSPATH to traverse outside the WordPress installation directory and invoke unlink() on sensitive files such as wp-config.php and .htaccess, causing site outage or enabling malicious reinstallation.
