How to Fix CVE-2022-39353

To remediate this vulnerability, upgrade all affected Xmldom dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

xmldom fixed: Latest secure release
npm install xmldom@Latest secure release
@xmldom/xmldom fixed: 0.7.7
npm install @xmldom/xmldom@0.7.7
@xmldom/xmldom fixed: 0.8.4
npm install @xmldom/xmldom@0.8.4
@xmldom/xmldom fixed: 0.9.0-beta.4
npm install @xmldom/xmldom@0.9.0-beta.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

npm ls xmldom

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-39353, inspect your project dependencies using npm:

npm ls xmldom

Analyze the terminal output to locate any version of Xmldom in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.7), your application is affected.

Note: The npm ls xmldom command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Xmldom, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact xmldom parses XML that is not well-formed because it contains multiple top level elements, and adds all root nodes to the `childNodes` collection of the `Document`, without reporting any error or throwing. This breaks the assumption that there is only a single root node in the tree, which led to https://nvd.nist.gov/vuln/detail/CVE-2022-39299 and is a potential issue for dependents. ### Patches Update to `@xmldom/xmldom@~0.7.7`, `@xmldom/xmldom@~0.8.4` (dist-tag `latest`) or `@xmldom/xmldom@>=0.9.0-beta.4` (dist-tag `next`). ### Workarounds One of the following approaches might help, depending on your use case: - Instead of searching for elements in the whole DOM, only search in the `documentElement`. - Reject a document with a document that has more then 1 `childNode`. ### References - https://nvd.nist.gov/vuln/detail/CVE-2022-39299 - https://github.com/jindw/xmldom/issues/150 ### For more information If you have any questions or comments about this advisory: * Email us at security@xmldom.org
