PHP Code Injection in SuiteCRM via Studio Dropdown Editor

Publication date: 2026-11-05

Last updated on: 2026-11-05

Assigner: GitHub, Inc.

Description
SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the Studio Dropdown Editor passes $dropdown_name through html_entity_decode() and writes the result verbatim into a PHP language file under custom/ that is included on later page loads. An administrator can inject persistent PHP that executes as the web-server account, survives cache clears, and compromises application and host confidentiality, integrity, and availability. This issue is fixed in versions 7.15.2 and 8.10.2.

Executive Summary

This is a critical remote code execution (RCE) vulnerability in SuiteCRM versions 8.10.1 and below, as well as 7.15.1 and below. It allows an administrator to inject persistent PHP code into a file under custom/ via the Studio Dropdown Editor. The injected code executes as the web server user (www-data), creating a persistent server-side webshell that survives cache clears and reboots.

Detection Guidance

Check SuiteCRM versions below 7.15.2 or 8.10.2 for vulnerable installations. Inspect custom/ directory for unexpected PHP files or modifications. Look for admin activity in logs that may indicate Dropdown Editor usage.

Impact Analysis

An attacker with administrator access can execute arbitrary OS commands, compromising the entire application and host. This includes full control over data confidentiality, integrity, and availability. The webshell persists even after cache clearing or reboots, making it difficult to remove.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection (GDPR, HIPAA) due to unauthorized code execution, potential data breaches, and loss of system integrity. Full compromise of the application and host could lead to unauthorized access to sensitive data, triggering mandatory breach notifications.

Mitigation Strategies

Upgrade SuiteCRM to versions 7.15.2 or 8.10.2 immediately. Remove any unauthorized PHP files in custom/ directory. Review admin accounts for suspicious activity. Apply principle of least privilege to admin roles.
