At a glance
CVE-2026-3177 is a medium-severity Insufficient Verification of Data Authenticity vulnerability in the Charitable WordPress plugin, affecting versions <= 1.8.9.7. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.8.10; sites on affected versions should update now. Disclosed April 2026, reported by Andrés Cruciani.
Vulnerability Overview
The Charitable – Donation Plugin for WordPress – Fundraising with Recurring Donations & More plugin for WordPress is vulnerable to Insufficient Verification of Data Authenticity in versions up to, and including, 1.8.9.7. This is due to missing cryptographic verification of incoming Stripe webhook events. This makes it possible for unauthenticated attackers to forge payment_intent.succeeded webhook payloads and mark pending donations as completed without a real payment.
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 privileges on the target site, and no interaction from a victim user.
CWE-345: Insufficient Verification of Data Authenticity
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
Remediation
Update to version 1.8.10, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Charitable 1.8.10 closes this, and updating the plugin is the step that ends it.
