# CVE-2026-92615: Flightctl: flightctl: package-global go-git https transport mutated per-repo -- cross-tenant tls-config bleed

Status: published. Published: 2026-09-16. Updated: 2026-11-03.

A flaw was found in flightctl. The configureRepoHTTPSClient() function in the device-render worker builds a per-repository tls.Config (which may include InsecureSkipVerify, a custom CA bundle, or tenant-supplied mTLS client certificates) and installs it into go-git's process-global client.Protocols map via gitclient.InstallProtocol("https", ...). Because the worker renders devices for multiple organizations concurrently from a shared goroutine pool, whichever tenant's repository configuration is written last wins for all in-flight git.Clone calls. 
This race condition can cause one tenant's TLS settings, including InsecureSkipVerify or mTLS client credentials, to leak into another tenant's git operations.

## Remediation

- workaround: There is no application-level workaround that fully eliminates this race condition without a code change. The following deployment-level measures reduce exposure in multi-tenant environments:
- Avoid mTLS client certificates for git repositories: If tenant Repository resources do not supply client TLS certificates (httpConfig.tls.clientCertificate), the most sensitive data (client private key material) is absent from the global transport and cannot leak.
- Avoid skipServerVerification: Do not set httpConfig.skipServerVerification: true on any Repository resource. This prevents a tenant's InsecureSkipVerify=true from propagating to other tenants' clones, which would otherwise allow an on-path attacker to serve malicious configuration. (source: CNA: redhat)
