CVE-2026-29103

Suitecrm remote code execution

9.1 CRITICALEPSS 0.89%
  1. Published19 Mar 2026

Description

SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. A Critical Remote Code Execution (RCE) vulnerability exists in SuiteCRM 7.15.0 and 8.9.2, allowing authenticated administrators to execute arbitrary system commands. This vulnerability is a direct Patch Bypass of CVE-2024-49774. Although the vendor attempted to fix the issue in version 7.14.5, the underlying flaw in ModuleScanner.php regarding PHP token parsing remains. The scanner incorrectly resets its internal state ($checkFunction flag) when encountering any single-character token (such as =, ., or ;). This allows attackers to hide dangerous function calls (e.g., system(), exec()) using variable assignments or string concatenation, completely evading the MLP security controls. Versions 7.15.1 and 8.9.3 patch the issue.
