Technical details

An authorization bypass exists in Gitea's API due to an incomplete fix for a previous vulnerability. While public member listing endpoints were secured, the 'ListMembers' function in 'routers/api/v1/org/member.go' lacks a visibility check. An authenticated attacker can send a GET request to '/api/v1/orgs/{org}/members' to retrieve a full list of members, including their login names and email addresses, for organizations they do not have permission to view. This vulnerability is addressed in version 1.27.0 by adding the missing 'HasOrgOrUserVisible' check.
