How to Fix CVE-2021-32859

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

baremetrics-calendar fixed: Latest secure release 
npm install baremetrics-calendar@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 baremetrics-calendar

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-32859, inspect your project dependencies using npm:

npm ls baremetrics-calendar

Analyze the terminal output to locate any version of Baremetrics calendar 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 baremetrics-calendar 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Baremetrics calendar, 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

The Baremetrics date range picker is a solution for selecting both date ranges and single dates from a single calender view. Versions 1.0.14 and prior are prone to cross-site scripting (XSS) when handling untrusted `placeholder` entries. An attacker who is able to influence the field `placeholder` when creating a `Calendar` instance is able to supply arbitrary `html` or `javascript` that will be rendered in the context of a user leading to XSS. There are no known patches for this issue.
