How to Fix GHSA-vf6x-59hh-332f

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

getformwork/formwork fixed: 2.0.0-beta.4 
Upgrade getformwork/formwork to 2.0.0-beta.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for getformwork/formwork

How to Check if You Are Affected

To determine whether your application is affected by GHSA-vf6x-59hh-332f, inspect your project dependencies for Getformwork/formwork:

inspect dependencies for getformwork/formwork

Analyze the terminal output to locate any version of Getformwork/formwork in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.0-beta.4), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. In Getformwork/formwork, 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

### Summary The site title field at /panel/options/site/allows embedding JS tags, which can be used to attack all members of the system. This is a widespread attack and can cause significant damage if there is a considerable number of users. ### Impact The attack is widespread, leveraging what XSS can do. This will undoubtedly impact system availability. ### Patches - [**Formwork 2.x** (aa3e9c6)](https://github.com/getformwork/formwork/commit/aa3e9c684035d9e8495169fde7c57d97faa3f9a2) escapes site title from panel header navigation. ### Details By embedding "<!--", the source code can be rendered non-functional, significantly impacting system availability. However, the attacker would need admin privileges, making the attack more difficult to execute.
