At a glance

CVE-2026-14326 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the Timetics WordPress plugin, affecting versions < 1.0.62. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Staff level or above. The issue is fixed in version 1.0.62; sites on affected versions should update now. Disclosed August 2026, reported by Sujin.

Vulnerability Overview

The Timetics plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and excluding, 1.0.62. This is due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with staff-level access and above, to perform an unauthorized action.

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.

CWE-639: Authorization Bypass Through User-Controlled Key

Reaching this weakness in Timetics < 1.0.62 takes an account at Staff level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Timetics the fix is 1.0.62: builds < 1.0.62 are affected, anything from 1.0.62 onward is not.

Remediation

Update to version 1.0.62, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Timetics 1.0.62 closes this, and updating the plugin is the step that ends it.
