CVE-2022-3082 is a vulnerability identified in the miniOrange Discord Integration WordPress plugin versions prior to 2.1.6. The core issue stems from missing authorization checks and lack of Cross-Site Request Forgery (CSRF) protections in certain AJAX actions within the plugin. This flaw allows any authenticated user, including those with minimal privileges such as subscribers, to invoke these AJAX endpoints. Exploiting this vulnerability, an attacker can perform unauthorized actions like disabling the Discord integration app, which can disrupt communication workflows reliant on this plugin. The vulnerability is categorized under CWE-862 (Missing Authorization) and CWE-352 (Cross-Site Request Forgery), highlighting the absence of proper access control and CSRF mitigation mechanisms. The CVSS v3.1 base score is 6.5 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), no confidentiality or integrity impact (C:N, I:N), but high availability impact (A:H). This means the vulnerability can be exploited remotely by any logged-in user without additional user interaction, leading to denial of service or disruption of plugin functionality. No known exploits are currently reported in the wild, and no official patches are linked in the provided data, though upgrading to version 2.1.6 or later is implied to remediate the issue.

For European organizations using WordPress sites with the miniOrange Discord Integration plugin, this vulnerability poses a risk primarily to the availability of integrated Discord communication channels. Disabling the app could interrupt critical team communications, notifications, or automated workflows that depend on Discord integration, potentially affecting operational efficiency and incident response capabilities. Since the exploit requires only a low-privilege authenticated user, insider threats or compromised low-level accounts could be leveraged to disrupt services. While confidentiality and integrity are not directly impacted, the availability disruption could have cascading effects, especially for organizations relying heavily on Discord for internal or external communications. This is particularly relevant for sectors with stringent operational continuity requirements such as finance, healthcare, and government institutions in Europe. Additionally, the lack of CSRF protection increases the risk of attackers tricking authenticated users into performing unwanted actions, further broadening the attack surface.

European organizations should immediately audit their WordPress installations for the presence of the miniOrange Discord Integration plugin and verify the version in use. Upgrading the plugin to version 2.1.6 or later, where authorization and CSRF protections are presumably implemented, is the primary mitigation step. If upgrading is not immediately feasible, organizations should restrict plugin usage to trusted users only, minimizing the number of accounts with login access to the WordPress backend. Implementing Web Application Firewall (WAF) rules to detect and block suspicious AJAX requests targeting the plugin’s endpoints can provide temporary protection. Additionally, monitoring WordPress logs for unusual AJAX activity or unexpected disabling of the Discord app can help detect exploitation attempts. Organizations should also enforce strong authentication and session management policies to reduce the risk of low-privilege account compromise. Finally, educating users about CSRF risks and ensuring that all plugins follow secure coding practices is recommended to prevent similar vulnerabilities.
