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.","state":0,"publishedAt":"2026-10-14T19:17:05.7+00:00","modifiedAt":"2026-10-15T16:17:32.45+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":9.2,"severity":"CRITICAL"}],"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"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-102748","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-306","CWE-862"],"productCriteria":[],"sourceDates":{"published":"2026-10-14T19:17:05.700","lastModified":"2026-10-15T16:17:32.450"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
