{"id":"GHSA-5xf3-gmx4-529v","summary":"Grafana Tempo Operator Vulnerable to Exposure of Sensitive Information to an Unauthorized Actor","details":"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.\nThis 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.","aliases":["CVE-2025-2842","GO-2026-5161"],"modified":"2026-06-25T18:56:47.278880658Z","published":"2025-04-02T15:31:36Z","database_specific":{"nvd_published_at":"2025-04-02T12:15:14Z","cwe_ids":["CWE-200"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-05-11T13:53:11Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-2842"},{"type":"WEB","url":"https://github.com/grafana/tempo-operator/pull/1144"},{"type":"WEB","url":"https://github.com/grafana/tempo-operator/commit/60b538c45f76755262e211d8df0e601a716308c7"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2025:3607"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2025:3740"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2025-2842"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2355219"},{"type":"PACKAGE","url":"https://github.com/grafana/tempo-operator"},{"type":"WEB","url":"https://github.com/grafana/tempo-operator/blob/8d1c7f13cb0f8db490144b04665b1fd6a2d56307/CHANGELOG.md?plain=1#L342"}],"affected":[{"package":{"name":"github.com/grafana/tempo-operator","ecosystem":"Go","purl":"pkg:golang/github.com/grafana/tempo-operator"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.16.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/04/GHSA-5xf3-gmx4-529v/GHSA-5xf3-gmx4-529v.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
