At a glance
CVE-2026-24985 is a medium-severity Missing Authorization vulnerability in the WP Forms Signature Contract Add-On WordPress plugin, affecting versions <= 1.8.2. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.8.3; sites on affected versions should update now. Disclosed January 2026, reported by Nabil Irawan.
Vulnerability Overview
The WP Forms Signature Contract Add-On plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 1.8.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to dismiss notices.
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 WP Forms Signature Contract Add-On <= 1.8.2 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 WP Forms Signature Contract Add-On the fix is 1.8.3: builds <= 1.8.2 are affected, anything from 1.8.3 onward is not.
Remediation
Update to version 1.8.3, 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: WP Forms Signature Contract Add-On 1.8.3 closes this, and updating the plugin is the step that ends it.
