According to the news at https://gnupg.org:

--8<---------------cut here---------------start------------->8---
Libgcrypt 1.9.1 released (2021-01-29)   important

Unfortunately we introduced a severe bug in Libgcrypt 1.9.0 released 10 days ago.
If you already started to use version 1.9.0 please update immediately to 1.9.1.

Currently the master and staging branch are using libgcrypt 1.8.5 and
core-updates is using 1.8.7. These versions don't have the critical bug
as it was introduced in version 1.9.0. So I think updating libgcrypt on
master is not an emergency, we just have to remember to never use
version 1.9.0.
