The full story
A was found Vulnerability Tracked as CVE-2025-2842. No exploitation flag is present in the retained CyberDeltaForce data at this time; that status can change as vendor and threat-intelligence reporting develops. CVE-2025-2842 is a newly disclosed security weakness in the affected technology.
A flaw was found in the Tempo Operator. A security weakness in the affected technology is being tracked as CVE-2025-2842. CVE-2025-2842 currently carries a MEDIUM 4 3 severity signal in the retained vulnerability data.
the development is primarily about a software weakness. Risk depends on whether the affected product and versions are present, whether the vulnerable function is reachable, whether exploitation is public or active, and what privileges the affected process carries. The issue currently carries a MEDIUM 4 3 severity signal in the CyberDeltaForce record.
The operational question is not simply the severity score, but whether the affected component is deployed, reachable, business-critical and protected by compensating controls. If you use the affected technology, first check whether the vulnerable component is actually present and reachable. The current severity assessment is MEDIUM 4 3.
Real risk depends on exposure, exploitability, compensating controls and the importance of the affected asset—not the CVSS number alone. The issue is tracked as CVE-2025-2842. The current record lists the severity as MEDIUM 4.3.
The current record does not mark the vulnerability as actively exploited. NIST NVD published the primary report used for this article on Sep 7, 2026. Inventory affected products and versions.
Validate external and internal reachability of the vulnerable function. Apply the vendor fix or mitigation and review telemetry for exploitation indicators when available. The story is primarily about a software weakness.

A flaw was found in the Tempo Operator. When the Jaeger UI Monitor Tab functionality is enabled in a Tempo instance managed by the Tempo Operator, the Operator creates a ClusterRoleBinding for the Service Account of the Tempo instance to grant the cluster-monitoring-view ClusterRole. This can be exploited if a user has 'create' permissions on TempoStack and 'get' permissions on Secret in a namespace (for example, a u

What this means
The story is primarily about a software weakness. Risk depends on whether the affected product and versions are present, whether the vulnerable function is reachable, whether exploitation is public or active, and what privileges the affected process carries.
What security teams should check now
- Inventory affected products and versions.
- Validate external and internal reachability of the vulnerable function.
- Apply the vendor fix or mitigation and review telemetry for exploitation indicators when available.
What is not yet confirmed
- Available reporting does not currently indicate exploitation, but that can change as vendor, government or threat-intelligence reporting develops.
