How to Fix GHSA-3c5g-73f7-grvm

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

neos/neos fixed: 3.0.20
Upgrade neos/neos to 3.0.20
neos/neos fixed: 3.1.18
Upgrade neos/neos to 3.1.18
neos/neos fixed: 3.2.14
Upgrade neos/neos to 3.2.14
neos/neos fixed: 3.3.23
Upgrade neos/neos to 3.3.23
neos/neos fixed: 4.0.17
Upgrade neos/neos to 4.0.17
neos/neos fixed: 4.1.16
Upgrade neos/neos to 4.1.16
neos/neos fixed: 4.2.12
Upgrade neos/neos to 4.2.12
neos/neos fixed: 4.3.3
Upgrade neos/neos to 4.3.3
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 neos/neos

How to Check if You Are Affected

To determine whether your application is affected by GHSA-3c5g-73f7-grvm, inspect your project dependencies for Neos/neos:

inspect dependencies for neos/neos

Analyze the terminal output to locate any version of Neos/neos in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.20), 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 General Security Weakness. In Neos/neos, 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

Due to reports it has been validated that internal workspaces in Neos are accessible without authentication. Some users assumed this is a planned feature but it is not. A workspace preview should be an additional feature with respective security measures in place. Note that this only allows reading of internal workspaces not writing. And for clarification, an internal workspace is a workspace that is non public and doesn't have an owner. Given that an internal workspace exists in your installation, it is possible to view a page in context of that workspace by opening a link in this format: https://domain/path/to/page.html@workspace-name The issue is quite problematic when exploited but at the same time slightly less impactful than it sounds. First of all there is no default internal workspace, so the issue affects only workspaces created by users. That also means the workspace-name, which will also always include a hash is individual to a project and an exploiter must get hold of the workspace-name including the hash. This is non trivial as there is no indication of the existence of it, but obviously brute force and educated guessed can be made.
