Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2026-33288 impacting suitecrm suitecrm. Evaluated with CVSS Base Score of 8.8 (HIGH).

Original NVD Description

Source: NIST NVD
SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to versions 7.15.1 and 8.9.3, a SQL Injection vulnerability exists in the SuiteCRM authentication mechanisms when directory support is enabled. The application fails to properly sanitize the user-supplied username before using it in a local database query. An attacker with valid, low-privilege directory credentials can exploit this to execute arbitrary SQL commands, leading to complete privilege escalation (e.g., logging in as the CRM Administrator). Versions 7.15.1 and 8.9.3 patch the issue.
