How to Fix CVE-2020-26304

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

foundation-sites fixed: Latest secure release 
npm install foundation-sites@Latest secure release
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 foundation-sites

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-26304, inspect your project dependencies using npm:

npm ls foundation-sites

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

Note: The npm ls foundation-sites 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-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In Foundation sites, 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

Foundation is a front-end framework. Versions 6.3.3 and prior contain one or more regular expressions that are vulnerable to Regular Expression Denial of Service (ReDoS). As of time of publication, it is unknown if any fixes are available.
