At a glance
CVE-2026-17580 is a medium-severity Missing Authorization vulnerability in the Advanced Views WordPress plugin, affecting versions <= 3.9.1. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 3.9.2; sites on affected versions should update now. Disclosed July 2026, reported by Wordfence PRISM.
Vulnerability Overview
The Advanced Views – Display Custom Fields (ACF, Pods, MetaBox), Posts, CPT and Woo Products anywhere in Gutenberg, Elementor, Divi, Beaver… plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.9.1 via the register_rest_routes. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract sensitive admin-authored editor content — including template markup, CSS code, JavaScript code, and PHP controller variables — for any Layout or Post Selection post 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. A successful exploit has high impact on confidentiality.
CWE-862: Missing Authorization
Reaching this weakness in Advanced Views <= 3.9.1 takes an account at Subscriber 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 Advanced Views the fix is 3.9.2: builds <= 3.9.1 are affected, anything from 3.9.2 onward is not.
Remediation
Update to version 3.9.2, 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: Advanced Views 3.9.2 closes this, and updating the plugin is the step that ends it.
