Comment 2 Carl George 🤠 2023-01-24 03:33:35 UTC

The parent bug and upstream report indicate that the vulnerability exists prior to version 2.2.4.

epel9 has caddy 2.4.6, which vendors yaml 2.4.0, so it's not affected.

https://github.com/caddyserver/caddy/blob/v2.4.6/go.mod#L34

epel8 doesn't have caddy, so it's not affected.

epel7 has caddy 1.0.3, which vendors yaml 2.2.2, so it is affected.

https://github.com/caddyserver/caddy/blob/v1.0.3/go.mod#L24
