{"id":"CVE-2026-41492","summary":"Unauthenticated Admin Token Disclosure Leading to Authentication Bypass via /debug/vars in Dgraph","details":"Dgraph is an open source distributed GraphQL database. Prior to 25.3.3, Dgraphl exposes the process command line through the unauthenticated /debug/vars endpoint on Alpha. Because the admin token is commonly supplied via the --security \"token=...\" startup flag, an unauthenticated attacker can retrieve that token and replay it in the X-Dgraph-AuthToken header to access admin-only endpoints. This is a variant of the previously fixed /debug/pprof/cmdline issue, but the current fix is incomplete because it blocks only /debug/pprof/cmdline and still serves http.DefaultServeMux, which includes expvar's /debug/vars handler. This vulnerability is fixed in 25.3.3.","aliases":["GHSA-vvf7-6rmr-m29q","GO-2026-5675"],"modified":"2026-08-12T03:51:48.874546943Z","published":"2026-04-24T18:29:40.555Z","related":["CGA-q3pq-442c-mp5f","openSUSE-SU-2026:21483-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-200"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41492.json"},"references":[{"type":"WEB","url":"https://github.com/dgraph-io/dgraph/releases/tag/v25.3.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41492.json"},{"type":"ADVISORY","url":"https://github.com/dgraph-io/dgraph/security/advisories/GHSA-vvf7-6rmr-m29q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41492"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dgraph-io/dgraph","events":[{"introduced":"0"},{"fixed":"55e3b79817e87512297695f7dccae86130d0c81e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"25.3.3"}],"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:dgraph:dgraph:*:*:*:*:*:go:*:*"}}],"versions":["v25.3.2","v25.3.1","v25.3.0","v25.2.0","v25.1.0","v25.1.0-preview1","v25.0.0","v25.0.0-preview6","v25.0.0-preview5","v25.0.0-preview4","v25.0.0-preview3","v25.0.0-preview2","v25.0.0-preview1","v24.0.2","v24.0.2-rc1","v24.0.1","v24.0.0","v24.0.0-rc1","v23.1.0","v24.0.0-alpha3","v24.0.0-alpha2","v24.0.0-alpha","v23.1.0-rc1","v23.1.0-rc2","v23.0.1","v22.0.2","v23.0.0","v23.0.0-rc1","v23.0.0-beta1","v22.0.0","v22.0.0-RC1-20221003","v21.03.2","v21.03.1","v21.03.0","v20.11.0-rc1","release/v20.11-rc1","v1.0.8","v1.0.9","v2.0.0-rc1","v2.0.0-beta1","v1.2.0-rc1","v1.1.1","v1.1.1-rc2","v1.1.1-rc1","v1.1.0","v1.1.0-rc3","v1.1.0-rc2","v1.0.12-rc3","v1.0.12-rc2","v1.0.12-rc1","v1.0.11","v1.0.11-rc4","v1.0.11-rc3","v1.0.11-rc2","v1.0.10","v1.0.11-rc1","v1.0.10-rc1","v1.0.9-rc5","v1.0.9-rc4","v1.0.9-rc3","v1.0.9-rc2","v1.0.9-rc1","v1.0.8-rc2","v1.0.8-rc1","v1.0.7a","v1.0.7","v1.0.7-rc4","v1.0.7-rc3","v1.0.7-rc2","nightly","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v0.9.4","v0.9.0","v0.8.3","v0.8.1","v0.8.0","v0.4.2","v0.4.1","v0.4.0","v0.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41492.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
