At a glance

CVE-2023-1333 is a medium-severity Missing Authorization vulnerability in the RapidLoad AI WordPress plugin, affecting versions <= 1.7.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 1.7.2; sites on affected versions should update now. Disclosed March 2023, reported by Marco Wotschka.

Vulnerability Overview

The RapidLoad Power-Up for Autoptimize plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the clear_page_cache function in versions up to, and including, 1.7.1. This makes it possible for authenticated attackers with subscriber-level access to delete the plugin's cache.

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-862: Missing Authorization

Reaching this weakness in RapidLoad AI <= 1.7.1 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For RapidLoad AI the fix is 1.7.2: builds <= 1.7.1 are affected, anything from 1.7.2 onward is not.

Remediation

Update to version 1.7.2, 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: RapidLoad AI 1.7.2 closes this, and updating the plugin is the step that ends it.
