How to Fix GHSA-v78c-4p63-2j6c

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

moment-timezone fixed: 0.5.35 
npm install moment-timezone@0.5.35
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 moment-timezone

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-v78c-4p63-2j6c, inspect your project dependencies using npm:

npm ls moment-timezone

Analyze the terminal output to locate any version of Moment timezone in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.5.35), your application is affected.

Note: The npm ls moment-timezone 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-319: Cleartext Transmission of Sensitive Information, where the product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors. In Moment timezone, 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

### Impact * if Alice uses `grunt data` (or `grunt release`) to prepare a custom-build, moment-timezone with the latest tzdata from IANA's website * and Mallory intercepts the request to IANA's unencrypted ftp server, Mallory can serve data which might exploit further stages of the moment-timezone tzdata pipeline, or potentially produce a tainted version of moment-timezone (practicality of such attacks is not proved) ### Patches Problem has been patched in version 0.5.35, patch should be applicable with minor modifications to all affected versions. The patch includes changing the FTP endpoint with an HTTPS endpoint. ### Workarounds Specify the exact version of tzdata (like `2014d`, full command being `grunt data:2014d`, then run the rest of the release tasks by hand), or just apply the patch before issuing the grunt command.
