How to Fix CVE-2021-23682
To remediate this vulnerability, upgrade all affected Litespeed.js 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 litespeed.js@0.3.12Upgrade appwrite/server-ce to 0.12.2Upgrade appwrite/server-ce to 0.11.1Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls litespeed.jsHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2021-23682, inspect your project dependencies using npm:
npm ls litespeed.jsAnalyze the terminal output to locate any version of Litespeed.js in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.3.12), your application is affected.
Note: The npm ls litespeed.js 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 Litespeed.js, 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.
