At a glance

CVE-2026-12102 is a low-severity Authorization Bypass Through User-Controlled Key vulnerability in the UsersWP WordPress plugin, affecting versions <= 1.2.63. It carries a CVSS score of 2.7 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Editor level or above. The issue is fixed in version 1.2.64; sites on affected versions should update now. Disclosed June 2026, reported by Pasindu Dilshan (K4PXD).

Vulnerability Overview

The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.2.63 via the 'user_id' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with editor-level access and above, to reset and permanently delete the avatar or banner image of any arbitrary user, including administrators, by clearing their avatar_thumb or banner_thumb metadata in the uwp_usermeta table.

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-639: Authorization Bypass Through User-Controlled Key

UsersWP <= 1.2.63 carries this weakness at user_id, and reaching it takes an account at Editor level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For UsersWP the fix is 1.2.64: builds <= 1.2.63 are affected, anything from 1.2.64 onward is not.

Remediation

Update to version 1.2.64, 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: UsersWP 1.2.64 closes this, and updating the plugin is the step that ends it.
