CVE-2023-28427: Matrix js sdk Prototype Pollution Vulnerability
HIGHCVE-2023-28427 is a HIGH (CVSS 8.2) prototype pollution vulnerability (CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')) affecting Matrix js sdk libraries in the npm ecosystem. The issue involves prototype pollution in matrix-js-sdk (part 2). Remediation is available by upgrading affected packages to version 24.0.0.
CVE-2023-28427 at a Glance
Security Impact
CVSS: 8.2
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H).
How to Fix CVE-2023-28427
To remediate this vulnerability, upgrade all affected Matrix js 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.
npm install matrix-js-sdk@24.0.0Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls matrix-js-sdkHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2023-28427, inspect your project dependencies using npm:
npm ls matrix-js-sdkAnalyze the terminal output to locate any version of Matrix js sdk in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 24.0.0), your application is affected.
Note: The npm ls matrix-js-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-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), where the product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype. In Matrix js 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.
