{"id":"CVE-2026-41492","aliases":["GHSA-vvf7-6rmr-m29q","GO-2026-5675"],"url":"https://o3.security/vulnerability/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.","published":"2026-04-24T18:29:40.555Z","modified":"2026-08-07T11:51:03.781755811Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/dgraph-io/dgraph/v25","fixedVersion":"25.3.3"},{"ecosystem":"Go","name":"github.com/dgraph-io/dgraph/v24","fixedVersion":null},{"ecosystem":"Go","name":"github.com/dgraph-io/dgraph","fixedVersion":null}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:51:03.781755811Z"}}
