At a glance

CVE-2026-1860 is a medium-severity Missing Authorization vulnerability in the Kali Forms WordPress plugin, affecting versions <= 2.4.8. 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 2.4.9; sites on affected versions should update now. Disclosed February 2026, reported by Youssef Elouaer.

Vulnerability Overview

The Kali Forms plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.4.8. This is due to the `get_items_permissions_check()` permission callback on the `/kaliforms/v1/forms/{id}` REST API endpoint only checking for the `edit_posts` capability without verifying that the requesting user has ownership or authorization over the specific form resource. This makes it possible for authenticated attackers, with Contributor-level access and above, to read form configuration data belonging to other users (including administrators) by enumerating form IDs. Exposed data includes form field structures, Google reCAPTCHA secret keys (if configured), email notification templates, and server paths.

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

Kali Forms <= 2.4.8 carries this weakness at get_items_permissions_check(), and reaching it 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 Kali Forms the fix is 2.4.9: builds <= 2.4.8 are affected, anything from 2.4.9 onward is not.

Remediation

Update to version 2.4.9, 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: Kali Forms 2.4.9 closes this, and updating the plugin is the step that ends it.
