{"id":"CVE-2026-102748","published":"2026-10-14T19:17:05.700","lastModified":"2026-10-15T16:17:32.450","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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-306","CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/dgraph-io/dgraph/commit/c32f6041387fa631dbc057e265b71aec3384ead1","tags":[]},{"url":"https://github.com/dgraph-io/dgraph/releases/tag/v25.4.0","tags":[]},{"url":"https://github.com/dgraph-io/dgraph/security/advisories/GHSA-qj98-gp63-54xj","tags":[]}],"exploitRefs":[{"url":"https://github.com/dgraph-io/dgraph/commit/c32f6041387fa631dbc057e265b71aec3384ead1","tags":[]},{"url":"https://github.com/dgraph-io/dgraph/releases/tag/v25.4.0","tags":[]},{"url":"https://github.com/dgraph-io/dgraph/security/advisories/GHSA-qj98-gp63-54xj","tags":[]}],"hasPoc":true,"ai":null}
