CVE-2025-2842 | Tempo-operator: tempo operator token exposition lead to read sensitive data

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 user has ClusterAdmin permissions for a specific namespace), as the user can read the token of the Tempo service account and therefore has access to see all cluster metrics.

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
