How to Fix GHSA-43cf-7f3h-38rg

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: 1.1.3
Upgrade neos/neos to 1.1.3
neos/neos fixed: 1.2.3
Upgrade neos/neos to 1.2.3
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-43cf-7f3h-38rg, inspect your project dependencies for Neos/neos:

inspect dependencies for neos/neos
