Vulnerability Overview

The Contact Form 7 + Telegram plugin for WordPress is vulnerable to unauthorized modification of data and loss of data due to a missing capability check on the 'wpcf7_Telegram::ajax' function in versions up to, and including, 0.8.5. This makes it possible for authenticated attackers, with subscriber-level access and above, to approve, pause and refuse subscriptions.

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 Message Bridge for Contact Form 7 and Telegram <= 0.8.5 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 Message Bridge for Contact Form 7 and Telegram the fix is 0.8.6: builds <= 0.8.5 are affected, anything from 0.8.6 onward is not.

Remediation

Update to version 0.8.6, 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: Message Bridge for Contact Form 7 and Telegram 0.8.6 closes this, and updating the plugin is the step that ends it.
