What is CVE-2026-92615?
CVE-2026-92615 is a medium-severity vulnerability in Red Hat Advanced Cluster Management for Kubernetes 2, published on 16 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
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.
