Prior to 1.0.2, the default-on `POST /v1/workspaces/:workspace_id/projects/:project_id/github/connect/complete` endpoint in `internal/api/router.go` accepts `installation_id` from the request body or `X-GitHub-Installation-ID` header without verifying the installation belongs to the caller's workspace. `CompleteGitHubConnection` in `internal/api/github_connect.go` rigorously binds `state` to the caller's tenant, workspace, and project, but checks only that the installation ID is positive before persisting it as the caller's connection. `ListInstallationRepositories` in `internal/connectors/github/repositories.go` invokes token creation through `internal/connectors/github/app.go` and `POST /app/installations/{installationId}/access_tokens`, using the application's JWT. An authenticated tenant who starts a legitimate connection can supply another customer's non-secret installation ID to read the victim organization's private repository inventory, content, and metadata or drive posture scans, provided identrail's GitHub App is installed there. The default-off V2 `CompleteGitHubConnector` path shares the installation-ownership gap and additionally matches pending `state` without rechecking caller scope. This issue is fixed in version 1.0.2.","state":0,"publishedAt":"2026-10-28T13:15:53.456+00:00","modifiedAt":"2026-10-28T13:15:53.456+00:00","affected":[{"ecosystem":"Vendor product","name":"identrail","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"identrail\",\n                    \"product\": \"identrail\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.0.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","score":8.5,"severity":"HIGH"}],"references":["https://github.com/identrail/identrail/security/advisories/GHSA-cp3j-m783-3ph5","https://github.com/identrail/identrail/commit/835e40517509d6ef5405c27fbf14f579bedff0e7","https://github.com/identrail/identrail/releases/tag/v1.0.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-59185","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-59185","identifiers":["CVE-2026-59185"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
