At a glance

CVE-2026-73350 is a medium-severity Improper Authentication vulnerability in the SupportCandy WordPress plugin, affecting versions <= 3.5.1. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.5.2; sites on affected versions should update now. Disclosed August 2026, reported by hackthesoul.

Vulnerability Overview

The SupportCandy – AI Customer Support Ticket System & Live Chatbot Agent plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 3.5.1. This makes it possible for unauthenticated attackers 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 privileges on the target site, and no interaction from a victim user.

CWE-287: Improper Authentication

Reaching this weakness in SupportCandy <= 3.5.1 takes a caller who can reach the endpoint. Improper authentication means the mechanism that proves who a caller is can be satisfied without the secret it was supposed to require.

An attacker authenticates as another user — administrators included — without ever knowing a password, so password policies and login rate limits never come into play. For SupportCandy the fix is 3.5.2: builds <= 3.5.1 are affected, anything from 3.5.2 onward is not.

Remediation

Update to version 3.5.2, 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: SupportCandy 3.5.2 closes this, and updating the plugin is the step that ends it.
