# BA-Workflow: SQL injection lets logged-in attackers read, change, delete data

BA-Workflow (YS-infoware) before v3.6 has an SQL injection. Any authenticated low-privilege user can run arbitrary SQL over the network to read, modify or delete database contents. CVSS 8.8 (v3.1) / 8.7 (v4.0). Part of a TWCERT/CC bundle of three SQLi CVEs; CVE-2026-113407 needs v3.6.2.7.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:BA-Workflow affected < 3.6 fixed 3.6

## How to check

Check the installed BA-Workflow version (admin/about page or install package). Anything below 3.6 is affected. Vendor gives no other check steps.
