The affected and patched versions for web-token/jwt-framework were incorrect, the ones for web-token/jwt-library were correct.
See: https://github.com/web-token/jwt-framework/releases

I also had to change the string CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:P to CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N in order to submit this form, as the former wasn't being accepted. I have no idea how this works, so hopefully that's not a mistake on my end...
