{"apiVersion":"1.0","identifier":"CVE-2026-75889","description":"Grafana Alloy-s prometheus.operator.servicemonitors component allows a user who can create or modify ServiceMonitor resources in a watched namespace to specify an arbitrary local file through bearerTokenFile. Alloy reads the file and sends its contents as a bearer token to an attacker-controlled scrape endpoint. This may disclose files accessible to the Alloy process, including its projected Kubernetes service account token, potentially granting the attacker Alloy-s Kubernetes permissions. Exploitation requires ServiceMonitor write access and lower privileges than Alloy-s service account.","publishedAt":"2026-08-27T20:18:37","lastModifiedAt":"2026-08-28T16:18:25","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75889","cvssScore":7.7,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","epssProbability":0.00219,"riskScore":0.79,"affectedProduct":"Grafana Alloy","affectedVersions":"unknown","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-75889","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-75889","en":"https://www.redsauce.net/en/cves/CVE-2026-75889","fr":"https://www.redsauce.net/fr/cves/CVE-2026-75889","pt":"https://www.redsauce.net/pt/cves/CVE-2026-75889","de":"https://www.redsauce.net/de/cves/CVE-2026-75889","sk":"https://www.redsauce.net/sk/cves/CVE-2026-75889","el":"https://www.redsauce.net/el/cves/CVE-2026-75889"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-75889"}}
