How to Fix CVE-2024-42347

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

matrix-react-sdk fixed: 3.105.1 
npm install matrix-react-sdk@3.105.1
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 matrix-react-sdk

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-42347, inspect your project dependencies using npm:

npm ls matrix-react-sdk

Analyze the terminal output to locate any version of Matrix react sdk in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.105.1), your application is affected.

Note: The npm ls matrix-react-sdk 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-359: Exposure of Private Personal Information to an Unauthorized Actor, where the product does not properly prevent a person's private, personal information from being accessed by actors who either (1) are not explicitly authorized to access the information or (2) do not have the implicit consent of the person about whom the information is collected. In Matrix react sdk, 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 A malicious homeserver could manipulate a user's account data to cause the client to enable URL previews in end-to-end encrypted rooms, in which case any URLs in encrypted messages would be sent to the server. Even if the CVSS score would be 4.1 ([AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N](https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N&version=3.1)) the maintainer classifies this as High severity issue. ### Patches This was patched in matrix-react-sdk 3.105.1. ### Workarounds Deployments that trust their homeservers, as well as closed federations of trusted servers, are not affected. ### References N/A.
