CVE-2021-43822: Jackalope Doctrine-Dbal Project Jackalope Doctrine-Dbal

High severity, CVSS 7.5. EPSS: 1% chance of exploitation in the next 30 days.

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.
