At a glance

CVE-2025-6989 is a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the KALLYAS - Creative eCommerce Multi-Purpose WordPress Theme WordPress theme, affecting versions <= 4.21.0. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 4.22.0; sites on affected versions should update now. Disclosed July 2025, reported by stealthcopter.

Vulnerability Overview

The Kallyas theme for WordPress is vulnerable to arbitrary folder deletion due to insufficient file path validation in the delete_font() function in all versions up to, and including, 4.21.0. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete arbitrary folders on the server.

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 interaction from a victim user. A successful exploit has high impact on integrity, availability.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

KALLYAS - Creative eCommerce Multi-Purpose WordPress Theme <= 4.21.0 carries this weakness at delete_font(), and reaching it takes an account at Contributor level or above. 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 KALLYAS - Creative eCommerce Multi-Purpose WordPress Theme the fix is 4.22.0: builds <= 4.21.0 are affected, anything from 4.22.0 onward is not.

Remediation

Update to version 4.22.0, or a newer patched version

How does WordSec protect against this?

An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: KALLYAS - Creative eCommerce Multi-Purpose WordPress Theme 4.22.0 closes this, and updating the theme is the step that ends it.
