{"cve":"CVE-2026-102748","nvd":{"published":"2026-10-14T19:17:05.700","modified":"2026-10-15T16:17:32.450","status":"Deferred","description":"Dgraph is an open source distributed GraphQL database. Prior to 25.4.0, Dgraph Zero registers administrative HTTP routes on port 6080 without authentication when the administrative interface is enabled. The /removeNode route accepts attacker-controlled id and group values and passes them to Server.RemoveNode, where group 0 can trigger ProposePeerRemoval. A remote unauthenticated attacker who can reach the Zero HTTP port can read topology through /state, allocate identifiers through /assign, access the exposed /moveTablet administrative route, or remove membership through /removeNode, disrupting the Zero control plane and destabilizing Alpha nodes that depend on Zero. The route registration occurs in dgraph/cmd/zero/run.go, and the demonstrated membership-removal path reaches Server.RemoveNode and ProposePeerRemoval. This issue is fixed in version 25.4.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:H","score":9.2},"cvss_v3":null,"cwes":["CWE-306","CWE-862"],"references":["https://github.com/dgraph-io/dgraph/commit/c32f6041387fa631dbc057e265b71aec3384ead1","https://github.com/dgraph-io/dgraph/releases/tag/v25.4.0","https://github.com/dgraph-io/dgraph/security/advisories/GHSA-qj98-gp63-54xj"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:59:28.494260111+00:00"},"epss":{"cve":"CVE-2026-102748","score":0.00486,"percentile":0.41588,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-qj98-gp63-54xj","url":"https://osv.dev/vulnerability/GHSA-qj98-gp63-54xj","summary":"Dgraph: Zero Unauthenticated HTTP Admin removeNode Denial of Service","modified":"2026-10-15T20:30:07.056401611Z","packages":[{"ecosystem":"Go","name":"github.com/dgraph-io/dgraph/v25","purl":"pkg:golang/github.com/dgraph-io/dgraph/v25","ranges":["<25.4.0"],"fixed":["25.4.0"]}]}],"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).
