CVE-2026-92433 in Patreon Plugin
Summary
by MITRE • 10/17/2026
The Patreon WordPress plugin before 1.10.0 does not verify a nonce when connecting the site to a Patreon account, allowing attackers to make a logged-in administrator re-link the integration to an attacker-controlled account via a crafted request (CSRF), taking over the site's Patreon integration.

The vulnerability identified in versions of the Patreon WordPress plugin prior to 1.10.0 represents a critical failure in access control mechanisms, specifically involving Cross-Site Request Forgery protections. The core technical flaw lies in the absence of nonce verification during the process that connects or reconnects a WordPress site to a Patreon account. In secure web application design, nonces are unique tokens generated for specific actions and sessions to ensure that requests originate from legitimate users who intended to perform those actions. By omitting this validation step when handling integration configuration changes, the plugin exposes administrators to manipulation through crafted HTTP requests. This oversight allows an attacker to exploit the authenticated session of a site administrator without requiring additional authentication factors or complex social engineering beyond luring the victim into triggering the malicious request.
From an operational perspective, the impact of this vulnerability is severe due to the high privilege level required for the action and the sensitive nature of the integration being modified. An attacker who successfully exploits this flaw can force a logged-in administrator to re-link the Patreon integration to an account controlled by the adversary. This effectively results in the takeover of the site's Patreon functionality, which may include access to subscriber data, financial transaction information associated with memberships, and control over content distribution channels tied to the platform. Since WordPress administrators typically have full control over the website’s codebase and settings, compromising their session through this specific vector can serve as a stepping stone for further exploitation, potentially leading to complete site compromise if other vulnerabilities are present or if the attacker leverages the gained access to inject malicious scripts or modify critical configuration files.
This vulnerability aligns with CWE-352, which describes Cross-Site Request Forgery (CSRF), where an application fails to verify that a request was intentionally initiated by the user. Furthermore, it relates to CWE-862, as it involves missing authorization checks for specific administrative functions. In terms of offensive security frameworks such as MITRE ATT&CK, this behavior corresponds to techniques involving account manipulation and potentially credential access if the integration handles sensitive tokens or keys that could be exfiltrated after re-linking. The lack of nonce validation is a fundamental deviation from secure coding standards recommended by organizations like OWASP for handling state-changing requests in web applications.
To mitigate this vulnerability, immediate action must be taken to update the Patreon WordPress plugin to version 1.10.0 or later, where the developers have presumably implemented proper nonce verification and other security hardening measures. For sites that cannot immediately upgrade, temporary mitigations include restricting access to the administrative dashboard through IP whitelisting if feasible, ensuring strong password policies are enforced for all administrator accounts, and utilizing multi-factor authentication plugins to add an additional layer of security against session hijacking or forced actions. Additionally, implementing Content Security Policy headers can help mitigate some aspects of cross-site scripting that might be used in conjunction with CSRF attacks, although the primary fix must address the server-side validation logic within the plugin itself. Regular auditing of third-party plugins for adherence to WordPress coding standards and secure development lifecycle practices is essential to prevent similar issues in future deployments.
