CVE-2026-34976Public exploitNetwork attack vector

Pre-auth database overwrite and file read via restoreTenant

Published Apr 6, 2026 · Updated Apr 6, 2026

Missing authorization in Dgraph before 25.3.1 allows remote attackers to overwrite databases, read server files, and perform SSRF. The restoreTenant mutation is absent from adminMutationMWConfig, so a nil middleware list sends attacker-controlled restore inputs directly to the resolver. Network access to the Alpha admin endpoint is sufficient; crafted backup locations can replace tenant data, probe local paths, or make server-side requests.
