CVE AND release note not enough tipping off for you?

it is absolutely not on maintainers of projects to proactively notify those who've forked the project. clear and transparent notices are exactly the right approach

Apologies I didn't see there had been a CVE. I completely retract my statement.

given the fact that they communicated about this as a CVE, and Forgejo is a fork of gitea, one could say that this is on Forgejo though.

Agreed, I didn't realise there had been a CVE.
