CVE-2026-58427: CWE-200 in Gitea Gitea Open Source Git Server
Private org member list leaked via /members API endpoint — incomplete fix for PR #38145
AI Analysis
Technical Summary
An information disclosure vulnerability exists in Gitea versions before 1.27.0 where the /orgs/{org}/members API endpoint improperly allows any authenticated user to enumerate all members of a private organization. This is caused by the ListMembers function lacking proper access control checks, unlike the fixed ListPublicMembers and IsPublicMember functions. The vulnerability is an incomplete fix related to PR #38145 and is tracked as CVE-2026-58427 with moderate severity. A patch is available in version 1.27.0.
Potential Impact
Authenticated users can access the full member list of private organizations, potentially exposing sensitive membership information that should be restricted. This information disclosure could aid attackers in reconnaissance but does not directly allow privilege escalation or code execution.
Mitigation Recommendations
Upgrade Gitea to version 1.27.0 or later, where the access control for the /orgs/{org}/members API endpoint has been properly fixed. Since a patch is available, applying the official fix is the recommended remediation.
