What is CVE-2026-53574?

EspoCRM, an open-source customer relationship management application, is vulnerable to SQL injection through the GET entity streamAttachments endpoint. This flaw allows authenticated non-administrative users to submit a carefully crafted 'where' parameter, potentially enabling them to execute complex queries. Such vulnerabilities could lead to unauthorized access to sensitive database information, including admin session tokens, thereby permitting privilege escalation. The issue is rectified in version 9.3.8.
