Detailsinfo

A vulnerability classified as problematic has been found in Red Hat Advanced Cluster Management for Kubernetes and Edge Manager (affected version unknown). Affected is the function configureRepoHTTPSClient of the component Device Render Worker. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at access.redhat.com. This vulnerability is traded as CVE-2026-92615 since 09/16/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Additional levels of successful authentication are necessary for exploitation. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 09/16/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
