CVE-2026-39496Network attack vector

Authenticated database disclosure via unprepared SQL query

Published Apr 8, 2026 · Updated Apr 8, 2026

SQL injection in YayCommerce YayMail 4.3.3 and earlier allows remote authenticated users to read sensitive database data through crafted input.

Shop Manager-level access or higher is required, and the documented impact is blind extraction of sensitive database information.
