I have prepared a draft 2.0.27-1+deb10u1 release for buster-security and uploaded it to mentors:
https://mentors.debian.net/debian/pool/main/i/inspircd/inspircd_2.0.27-1+deb10u1.dsc Just need a maintainer to review and sponsor it, and to work with the Security team to get this uploaded to buster-security. (Note the changelog needs to be changed from UNRELEASED to buster-security.) Update for the unstable (3.x) package to follow soon. Christian
