The recent discovery of CVE-2025-10380 has put a spotlight on server vulnerabilities in WordPress plugins. This vulnerability allows an authenticated attacker to execute arbitrary PHP code on affected servers. Here’s what every system administrator and hosting provider should know.

Incident Overview

The Advanced Views plugin for WordPress versions up to and including 3.7.19 is vulnerable to Server-Side Template Injection (SSTI). The issue stems from inadequate input sanitization and access control when handling custom Twig templates. This vulnerability can allow attackers with author-level access to manipulate server files and execute harmful commands.

Why It Matters for Server Admins and Hosting Providers

This vulnerability is critical for server security. Commonly, authenticated users have lower security restrictions. This incident illustrates significant risks even from supposedly limited access levels. Failing to address such vulnerabilities can lead to devastating data breaches, necessitating immediate action from all stakeholders.

Practical Mitigation Steps

• Update the Advanced Views plugin to the latest version immediately.
• Review and sanitize all custom Twig templates to prevent injection vulnerabilities.
• Restrict access to the Model panel to trusted users only.
• Monitor for suspicious activity by implementing a robust web application firewall.
• Conduct regular audits of server security protocols to identify weaknesses.
