Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.97%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Jackalope Doctrine-DBAL is an implementation of the PHP Content Repository API (PHPCR) using a relational database to persist data. In affected versions users can provoke SQL injections if they can specify a node name or query. Upgrade to version 1.7.4 to resolve this issue. If that is not possible, you can escape all places where `$property` is used to filter `sv:name` in the class `Jackalope\Transport\DoctrineDBAL\Query\QOMWalker`: `XPath::escape($property)`. Node names and xpaths can contain `"` or `;` according to the JCR specification. The jackalope component that translates the query object model into doctrine dbal queries does not properly escape the names and paths, so that a accordingly crafted node name can lead to an SQL injection. If queries are never done from user input, or if you validate the user input to not contain `;`, you are not affected.
