How to Fix CVE-2020-26289

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

date-and-time fixed: 0.14.2 
npm install date-and-time@0.14.2
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 date-and-time

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-26289, inspect your project dependencies using npm:

npm ls date-and-time

Analyze the terminal output to locate any version of Date and time in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.14.2), your application is affected.

Note: The npm ls date-and-time 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Date and time, software state validation or input boundaries are circumvented during processing.
