Prior to versions 3.5.3 and 3.11.3, the client_secret field in the Azure AD remote write OAuth configuration (storage/remote/azuread) was typed as string instead of Secret. Prometheus redacts fields of type Secret when serving the configuration via the /-/config HTTP API endpoint. Because the field was a plain string, the Azure OAuth client secret was exposed in plaintext to any user or process with access to that endpoint. This issue has been patched in versions 3.5.3 and 3.11.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200","CWE-312","CWE-256"],"references":["https://github.com/prometheus/prometheus/pull/18587","https://github.com/prometheus/prometheus/pull/18590","https://github.com/prometheus/prometheus/releases/tag/v3.11.3","https://github.com/prometheus/prometheus/releases/tag/v3.5.3","https://github.com/prometheus/prometheus/security/advisories/GHSA-wg65-39gg-5wfj"],"products":["prometheus:prometheus"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-42151","score":0.00352,"percentile":0.28876,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-wg65-39gg-5wfj","url":"https://osv.dev/vulnerability/GHSA-wg65-39gg-5wfj","summary":"Prometheus Azure AD remote write OAuth client secret exposed via config API","modified":"2026-09-09T15:45:44.428200363Z","packages":[{"ecosystem":"Go","name":"github.com/prometheus/prometheus","purl":"pkg:golang/github.com/prometheus/prometheus","ranges":[">=0.45.2 <0.311.3"],"fixed":["0.311.3"]}]},{"id":"GO-2026-5710","url":"https://osv.dev/vulnerability/GO-2026-5710","summary":"Prometheus Azure AD remote write OAuth client secret exposed via config API in github.com/prometheus/prometheus","modified":"2026-07-15T16:27:42.071811707Z","packages":[{"ecosystem":"Go","name":"github.com/prometheus/prometheus","purl":"pkg:golang/github.com/prometheus/prometheus","ranges":[">=0.45.2 <0.311.3"],"fixed":["0.311.3"]}]}],"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).
