DescriptionCVE.org

Missing Authorization vulnerability in raratheme Kalon kalon allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Kalon: from n/a through <= 1.2.9.

AnalysisAI

Improper access control in Kalon through version 1.2.9 enables unauthenticated remote attackers to modify data or configurations by exploiting misconfigured authorization checks. The vulnerability carries medium severity with a CVSS score of 5.3 and currently has no available patch.

Technical ContextAI

This vulnerability stems from CWE-862 (Missing Authorization), which occurs when the application fails to properly implement access control checks before allowing users to perform sensitive operations. The raratheme Kalon product, a WordPress theme component, is affected across versions from an unspecified baseline through version 1.2.9. The root cause involves incorrectly configured access control security levels that do not adequately validate user permissions or authentication status before processing requests. This is particularly dangerous in web application contexts where authorization checks should be enforced server-side regardless of client-side security controls, a principle that appears to have been neglected in the affected versions of Kalon.

RemediationAI

Immediately upgrade raratheme Kalon to a patched version beyond 1.2.9 as soon as available from the vendor. Check the WordPress theme repository or raratheme's official website for version 1.3.0 or later that addresses CWE-862 authorization checks. Until patching is possible, implement server-side access control enforcement at the web server or reverse proxy level by restricting access to sensitive theme endpoints to authenticated users only, implementing rate limiting on all data modification endpoints, and conducting an audit of recent logs for any signs of unauthorized modifications. Additionally, enable WordPress security hardening measures such as disabling direct file access to theme components and enforcing strong authentication on all administrative functions.
