## What is CVE-2026-53574?

CVE-2026-53574 is a high-severity SQL injection vulnerability in espocrm, published on 15 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

EspoCRM is an open source customer relationship management application. From 8.1.0 until 9.3.8, an authenticated non-administrator can submit a crafted where parameter to the GET entity streamAttachments endpoint because that query path permits complex expressions. Boolean-based blind SQL injection can extract arbitrary database information, including active administrator session tokens, and can enable full privilege escalation. This issue is fixed in version 9.3.8.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)
