Summary

An authenticated non-administrator can submit a crafted where parameter to the GET entity streamAttachments endpoint in EspoCRM from 8.1.0 before 9.3.8, because this query path permits complex expressions. The flaw is a boolean-based blind SQL injection (CWE-89) that can extract arbitrary database information, including active administrator session tokens, and enable full privilege escalation. The CVSS 3.1 base score is 7.6 (HIGH).
