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

BA-Workflow (YS-infoware) before 3.6.2.7 has a SQL injection (CWE-89). Any authenticated low-privilege user can run arbitrary SQL over the network to read, modify or delete database contents. CVSS 8.7 (v4), 8.8 (v3.1). Published 2026-10-20 via TWCERT/CC.

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

## Affected

- vendor:BA-Workflow affected < 3.6.2.7 fixed 3.6.2.7

## How to check

Check the installed BA-Workflow version in the product's admin/about page or install directory; anything below 3.6.2.7 is affected. Exact location is unknown: ask YS-infoware.

## Fix

Upgrade BA-Workflow to 3.6.2.7 or later (contact YS-infoware for the build). Until then, limit who has logins, restrict network access, and use a least-privilege database account.
