https://github.com/CenterForOpenScience/docker-library/blob/eabb0d50e3d347396a0aa8f0e7723c52e046630c/pgbouncer/Dockerfile#L1

The image built by this Dockerfile is 3 years old and and has a high-level vulnerability that has been patched in a newer version. For its base image, it uses a version of Alpine that reached end-of-support over a year ago.

It's old enough that security scanners are just saying 🤷‍♂️ or "The vulnerability detection may be insufficient because security updates are not provided".
