CVE-2025-62017

Vulnerability

Overview

The KALLYAS WordPress theme, versions up to and including 4.22.0, contains a missing authorization vulnerability. This issue arises from a lack of proper access control checks on certain theme functions, allowing unauthenticated users to perform actions that should require higher privileges [1]. The vulnerability is classified as a Broken Access Control issue, which is a common type of security flaw in WordPress themes and plugins.

Exploitation

Details

An attacker can exploit this vulnerability without any authentication or special privileges. By sending crafted HTTP requests to vulnerable endpoints within the theme, an unauthenticated user can bypass intended access restrictions [1]. The attack surface is broad, as the theme is widely used, and the vulnerability can be exploited remotely over the network.

Impact

Successful exploitation could allow an attacker to access sensitive data, modify theme settings, or perform other unauthorized actions. This could lead to further compromise of the WordPress site, including defacement, data theft, or injection of malicious content [1]. The vulnerability is considered medium severity (CVSS 5.4) but is often used in mass-exploit campaigns targeting thousands of sites.

Mitigation

The vendor has released a patched version (4.22.1 or later) to address this vulnerability. Users are strongly advised to update immediately. If updating is not possible, temporary workarounds such as restricting access to vulnerable endpoints via web server rules or using a security plugin can help reduce risk [1].
