要点
- CVE-2021-43822 は jackalope/jackalope-doctrine-dbal, jackalope doctrine-dbal (jackalope doctrine-dbal project) に影響する深刻度「高」 (CVSS 7.5) の脆弱性です。
- 今後30日間に悪用される確率（EPSS）：1.00%（全脆弱性の 63.0% より高い）。
- 対処：1.7.4 以降に更新してください。
概要
Impact
Users can provoke SQL injections if they can specify a node name or query.
Patches
Upgrade to version 1.7.4
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).
Workarounds
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.

NVD の説明
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.
