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.","state":0,"publishedAt":"2026-04-24T18:29:40.555+00:00","modifiedAt":"2026-04-24T19:13:03.267+00:00","affected":[{"ecosystem":"Vendor product","name":"dgraph","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"dgraph-io\",\n                    \"product\": \"dgraph\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 25.3.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/dgraph-io/dgraph/security/advisories/GHSA-vvf7-6rmr-m29q","https://github.com/dgraph-io/dgraph/releases/tag/v25.3.3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-41492","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-41492","identifiers":["CVE-2026-41492"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
