CVE-2021-43822

Date: December 13, 2021

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.
