Description

Doctrine DBAL 3.x before 3.1.4 allows SQL Injection. The escaping of offset and length inputs to the generation of a LIMIT clause was not probably cast to an integer, allowing SQL injection to take place if application developers passed unescaped user input to the DBAL QueryBuilder or any other API that ultimately uses the AbstractPlatform::modifyLimitQuery API.

Affected products

• Doctrine-Project Database Abstraction Layer: from 3.0.0 before 3.1.4 — fixed in 3.1.4

How to fix

Upgrade to a fixed version: Doctrine-Project Database Abstraction Layer 3.1.4. Check the vendor advisory for mitigations.
