At a glance
CVE-2026-7529 is a high-severity Missing Authorization vulnerability in the wiseCampaign WordPress plugin, affecting versions <= 1.1.14. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication. The issue is fixed in version 1.1.17; sites on affected versions should update now. Disclosed August 2026, reported by Legion Hunter.
Vulnerability Overview
The wiseCampaign – WooCommerce Conversions Made Easy plugin for WordPress is vulnerable to unauthorized modification and disclosure of data due to every one of its REST API endpoints being registered with `permission_callback => '__return_true'` in all versions up to, and including, 1.1.16. This makes it possible for unauthenticated attackers to read and modify the plugin's banner, stockbar, and core settings — including saving/updating banner records, toggling stockbar/feature flags, changing the active banner, and uploading background-image files via wp_handle_upload() — without any nonce or capability check.
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. A successful exploit has high impact on integrity.
CWE-862: Missing Authorization
wiseCampaign <= 1.1.14 carries this weakness at __return_true, and reaching it takes no account at all. 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 wiseCampaign the fix is 1.1.17: builds <= 1.1.14 are affected, anything from 1.1.17 onward is not.
Remediation
Update to version 1.1.17, or a newer patched version
How WordSec helps
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: wiseCampaign 1.1.17 closes this, and updating the plugin is the step that ends it.
