Mitigation checklist
- 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.
