What is CVE-2026-73033?

The Sucuri Security WordPress plugin, up to version 2.7.3, suffers from a path traversal vulnerability within the pageIntegritySubmission() method in src/integrity.lib.php. This flaw enables authenticated administrators to delete arbitrary files by inserting directory traversal sequences into the sucuriscan_integrity parameter. Attackers can exploit this by manipulating an unsanitized file path, allowing navigation outside the intended WordPress installation directory. This manipulation can lead to the deletion of sensitive files, including wp-config.php and .htaccess, potentially leading to site outages or enabling the malicious reinstallation of software.

Affected Version(s)

sucuri-wordpress-plugin 0 <= 2.7.3

Exploit Proof of Concept (PoC)
