CVE summarizes:

When a file is edited in a fork through the web editor, Gitea can first copy a branch from the base repository into the fork. That copy did not check whether the user may read the base repository's code. A user who had forked a repository and later lost access to it, for example after it was made private or they were removed as a collaborator, could keep copying its current branches into their fork and read them. The copy now requires read access to the code of the base repository.
