A SQL injection vulnerability exists in a database migration script in flowintel

A SQL injection vulnerability exists in a database migration script in flowintel.

The migration process reads stored connector identifier values from the database and interpolates them directly into SQL statements without parameterization. An attacker who has previously written a malicious identifier value into the affected tables can cause arbitrary SQL execution when the migration is subsequently run during an application upgrade.

• ■Requires prior write access to the database to plant a malicious identifier value
• ■Triggered automatically during a migration or upgrade operation
• ■Can result in unauthorized data disclosure, modification, or deletion

Affected versions: flowintel prior to 4.0.0
