A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Red Hat to 2.9.2.

AI-suggested

A fixed version 2.9.2 of the multicluster engine for Kubernetes has been released by Red Hat to address this vulnerability. Users should upgrade to version 2.9.2 or later to remediate the issue. No additional mitigations are specified or required beyond applying the official update.

Description

The multicluster engine for Kubernetes v2.9 images The multicluster engine for Kubernetes provides the foundational components that are necessary for the centralized management of multiple Kubernetes-based clusters across data centers, public clouds, and private clouds. You can use the engine to create new Red Hat OpenShift Container Platform clusters or to bring existing Kubernetes-based clusters under management by importing them. After the clusters are managed, you can use the APIs that are provided by the engine to distribute configuration based on placement policy.

Impact

The vulnerability can cause inconsistent data to be returned to applications using the affected multicluster engine for Kubernetes versions. It arises from a race condition when queries are cancelled during concurrent Scan operations. While it may cause unexpected behavior and data inconsistency, it is unlikely to lead to direct system compromise or privilege escalation in most typical deployments. The impact includes potential denial of service due to resource exhaustion or instability, and confidentiality or integrity issues due to race conditions in data handling.

Summary

CVE-2025-47907 is a race condition vulnerability in the database/sql package used by the multicluster engine for Kubernetes. When a query is cancelled during a Scan method call on returned Rows, concurrent queries can produce unexpected results due to a race condition. This can lead to inconsistent data being returned to the application. The vulnerability affects multicluster engine for Kubernetes versions >=2.9.0 and <2.9.2. Red Hat has issued a security update in version 2.9.2 to fix this issue. The flaw is classified under CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization) and related CWEs indicating race conditions and resource exhaustion. The vulnerability is rated as high severity by Red Hat but is noted to have limited exploitation scope and is unlikely to result in direct compromise in typical deployments.

CWE-362Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') (opens in a new tab)
Class weaknessLikelihood of exploit: MediumOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product contains a concurrent code sequence that 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 operating concurrently.
Architecture and Design
In languages that support it, use synchronization primitives. Only wrap these around critical code to minimize the impact on performance.
Architecture and Design
Use thread-safe capabilities such as the data access abstraction in Spring.
Architecture and Design
Minimize the usage of shared resources in order to remove as much complexity as possible from the control flow and to reduce the likelihood of unexpected conditions occurring.

CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.
