At a glance

CVE-2026-9050 is a medium-severity Missing Authorization vulnerability in the Slider Revolution WordPress plugin, affecting versions 6.0.0 – 7.0.14 · 2 branches. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 6.7.56; sites on affected versions should update now. Disclosed June 2026, reported by Nguyen Ngoc Duc (duc193).

Vulnerability Overview

The Slider Revolution plugin for WordPress in versions 6.0.0-6.7.55 and 7.0.0-7.0.14 is vulnerable to unauthorized modification of data. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with Contributor-level access and above, to deactivate any active plugin installed on the site.

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 Slider Revolution 6.0.0 – 7.0.14 · 2 branches takes an account at Contributor level or above. 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 Slider Revolution the fix is 6.7.56: builds 6.0.0 – 7.0.14 · 2 branches are affected, anything from 6.7.56 onward is not.

Remediation

Update to one of the following versions, or a newer patched version: 6.7.56, 7.0.15

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: Slider Revolution 6.7.56 closes this, and updating the plugin is the step that ends it.
