저도 본 이슈의 대응을 부탁드립니다. 현재 본 패키지가 사용중인 follow-redirects, axios 패키지에 보안 이슈가 있는 것으로 보입니다.
각각 다음과 같은 보안 문제를 포함하고 있습니다:

GHSA-4w2v-q235-vp99
GHSA-cph5-m8f7-6c5x
GHSA-74fj-2j2h-c42q
GHSA-pw2r-vq6v-hr8c

yarn audit은 follow-redirects >=1.14.8, axios >=0.21.2 를 사용할 것을 권고하고 있습니다.
package.json을 확인한 결과, follow-redirects는 axios의 의존성이니 이 부분 잘 참고해 주시길 부탁드립니다.
