How to Fix CVE-2021-3931

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

snipe/snipe-it fixed: Latest secure release 
Upgrade snipe/snipe-it to 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: 

inspect dependencies for snipe/snipe-it

How to Check if You Are Affected

To determine whether your application is affected by CVE-2021-3931, inspect your project dependencies for Snipe/snipe it:

inspect dependencies for snipe/snipe-it
