CVE-2025-4216: 
WordPress vulnerability analysis and mitigation

The DIOT SCADA with MQTT plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2025-4216) discovered in June 2025. The vulnerability affects all versions up to and including 1.0.5.1, stemming from insufficient input sanitization and output escaping on user-supplied attributes in the plugin's 'diot' shortcode (NVD CVE, Wiz).

The vulnerability has been assigned a CVSS v3.1 base score of 6.4 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N. The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation). The technical root cause is related to insufficient input sanitization and output escaping of user-supplied attributes in the plugin's 'diot' shortcode functionality (Wiz).

The vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever any user accesses the compromised page, potentially leading to data theft, session hijacking, or other client-side attacks (Wiz).

Users should update to a version newer than 1.0.5.1 when available. Until then, it is recommended to restrict contributor access and carefully monitor user permissions on WordPress installations using this plugin (Wiz).
