Description

We have released a new version Doctrine DBAL 3.1.4 that fixes a critical SQL injection vulnerability in the LIMIT clause generation API provided by the Platform abstraction.

We advise everyone using Doctrine DBAL 3.0.0 up to 3.1.3 to upgrade to 3.1.4 immediately.

The vulnerability can happen when unsanitized input is passed to many APIs in Doctrine DBAL and ORM that ultimately end up calling AbstractPlatform::modifyLimitQuery.

As a workaround you can cast all limit and offset parameters to integers before passing them to Doctrine APIs.

This vulnerability has been assigned CVE-2021-43608.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for doctrine/dbal, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update doctrine/dbal to 3.1.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2021-43608 is resolved across your whole dependency graph.

  3. Workarounds

    Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.
