CVE-2026-41327Public exploitNetwork attack vector

Unauthenticated database exfiltration via upsert condition injection

Published Apr 24, 2026 · Updated Apr 24, 2026

DQL injection in Dgraph before 25.3.3 allows remote attackers to read the entire database through an unauthenticated HTTP mutation. The buildUpsertQuery path rewrites @if to @filter, then appends the unvalidated cond value to a DQL string, allowing an injected named query block to execute and return its results. ACL-disabled deployments are exposed by default; with ACL enabled, remote authenticated users with mutation-only permission can bypass predicate read authorization.
