CVE-2026-91136
At a glance
CVE-2026-91136 is a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Divi Plus WordPress plugin, affecting versions <= 2.4.0. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 2.4.1; sites on affected versions should update now. Disclosed October 2026, reported by ShinThink.
Vulnerability Overview
The Divi Plus plugin for WordPress is vulnerable to Arbitrary File Read in versions up to, and including, 2.4.0 via the 'svg_image' parameter of the /wp-json/elicus/v1/dipl-modules/svg-animator REST endpoint. This is due to the endpoint's permission callback (SVGAnimatorController::index_permission) returning true unconditionally combined with insufficient validation of the 'svg_image' input — sanitize_text_field() and esc_html() do not restrict filesystem paths, the file:// stream wrapper, or arbitrary URLs — before it is passed to file_get_contents() (with a wp_remote_get() fallback) and the raw response body is returned in the JSON 'html' field. This makes it possible for unauthenticated attackers to read arbitrary files on the affected site's server which may make remote code execution possible.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Divi Plus <= 2.4.0 carries this weakness at svg_image, and reaching it takes no account at all. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.
Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Divi Plus the fix is 2.4.1: builds <= 2.4.0 are affected, anything from 2.4.1 onward is not.
Remediation
Update to version 2.4.1, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Divi Plus 2.4.1 closes this, and updating the plugin is the step that ends it.
