| Package | Affected versions | Patched versions |
|---|---|---|
| sequelize | ≤ 2.1.3 | |
| sequelize | < 3.0.0 | 3.0.0 |
Affected versions of sequelize are vulnerable to SQL Injection when user input is passed into findOne or into a statement such as where: "user input".
Update to version 3.0.0 or later.
Version 3.0.0 will introduce a number of breaking changes. Thankfully, the project authors have provided a 2.x -> 3.x upgrade guide to ease this transition.
If upgrading is not an option, it is also possible to mitigate this by ensuring that all uses of where: "input" and findOne("input") are properly sanitized, such as by the use of a wrapper function.
