At a glance
CVE-2026-5727 is a medium-severity Missing Authorization vulnerability in the Hello Plus WordPress plugin, affecting versions <= 1.7.7. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 1.7.8; sites on affected versions should update now. Disclosed October 2026, reported by normaandersonfrank.
Vulnerability Overview
The Hello Plus plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.7.7. 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 publish their own Hello+ header/footer templates and draft currently active templates owned by higher-privileged users.
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 Hello Plus <= 1.7.7 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 Hello Plus the fix is 1.7.8: builds <= 1.7.7 are affected, anything from 1.7.8 onward is not.
Remediation
Update to version 1.7.8, 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: Hello Plus 1.7.8 closes this, and updating the plugin is the step that ends it.
