{"cve":"CVE-2026-47701","nvd":{"published":"2026-09-14T16:17:11.540","modified":"2026-09-25T14:23:59.847","status":"Awaiting Analysis","description":"The OpenTelemetry Operator is a Kubernetes Operator for the OpenTelemetry Collector. Prior to 0.152.0, cmd/otel-allocator TargetAllocator instances with targetAllocator.prometheusCR.enabled set to true preserve a selected ServiceMonitor endpoint's bearerTokenFile value as HTTPClientConfig.Authorization.CredentialsFile. A tenant who can create or update a ServiceMonitor matched by serviceMonitorSelector and serviceMonitorNamespaceSelector can point bearerTokenFile at a file in the Collector pod, including /var/run/secrets/kubernetes.io/serviceaccount/token, and direct scraping to a tenant-controlled endpoint. The Collector reads that file at scrape time and sends its contents as bearer authorization on every scrape interval. Exploitation also requires the Collector service-account token or another sensitive file to be mounted and the Collector to reach the chosen target. The DenyFSAccessThroughSMs control was absent, allowing disclosure of the Collector's service-account JWT or other mounted files, and resulting Kubernetes API impact is limited by the Collector service account's permissions. This issue is fixed in version 0.152.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7},"cwes":["CWE-200"],"references":["https://github.com/open-telemetry/opentelemetry-operator/commit/95a8c2a3dc64a762d3ab8eba8c903b5702a03a9c","https://github.com/open-telemetry/opentelemetry-operator/pull/5104","https://github.com/open-telemetry/opentelemetry-operator/releases/tag/v0.152.0","https://github.com/open-telemetry/opentelemetry-operator/security/advisories/GHSA-cxh2-4639-vmc5"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-47701","score":0.0046,"percentile":0.39922,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cxh2-4639-vmc5","url":"https://osv.dev/vulnerability/GHSA-cxh2-4639-vmc5","summary":"OpenTelemetry Operator for Kubernetes's ServiceMonitor bearerTokenFile reads arbitrary local file and sends contents as bearer auth","modified":"2026-09-10T03:51:08.687091913Z","packages":[{"ecosystem":"Go","name":"github.com/open-telemetry/opentelemetry-operator","purl":"pkg:golang/github.com/open-telemetry/opentelemetry-operator","ranges":["<0.152.0"],"fixed":["0.152.0"]}]},{"id":"GO-2026-5339","url":"https://osv.dev/vulnerability/GO-2026-5339","summary":"OpenTelemetry Operator for Kubernetes's ServiceMonitor bearerTokenFile reads arbitrary local file and sends contents as bearer auth in github.com/open-telemetry/opentelemetry-operator","modified":"2026-06-25T19:45:31.867709302Z","packages":[{"ecosystem":"Go","name":"github.com/open-telemetry/opentelemetry-operator","purl":"pkg:golang/github.com/open-telemetry/opentelemetry-operator","ranges":["<0.152.0"],"fixed":["0.152.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
