Details: https://nvd.nist.gov/vuln/detail/CVE-2021-47865
This CVE was opened based on a 5 years old Github issue[1], and has been made public recently. The CVE wasn't officially disputed (yet?), but based on the description and the given PoC the application is working as expected. The vulnerability description and the PoC basically configures proftpd to accept maximum x connections, and then when the user tries to open x + 1 concurrent connections, it refuses new connections over the configured limit. See also discussion in the Github issue. I just put it on the ignore list.
